This paper presents a systematical numerical investigation into the lining performance of a tunnel with cavities around surrounding rocks, focusing on the influences of cavity size and multicavity distribution. The study demonstrates that the cavities around surrounding rocks have much influence on tunnel stability and may induce damages in tunnel structures, in which cavity width has a more severe effect on the stress state of tunnel structures than cavity depth. Moreover, the numerical investigation also illustrates that the nonadjacent distribution of multicavities has more serious influence on tunnel structures than that from adjacent distribution of multicavities as well as that from a single cavity.

Installing geosynthetic reinforcement at the bottom of the embankment will provide positive support for subgrade stability and settlement control, if there is a void or a weak foundation. In routine design work, the geomembrane effect must be well estimated and the tensile strain should be precisely predicted. Conventional analytical methods often adopt the limit state method to calculate the overlying load on the deflected geosynthetic. However, this assumption does not necessarily apply to all conditions, especially when the foundation soil can provide certain resistance. In this study, a semiempirical prediction method for evaluating the geomembrane effect of the basal reinforcement was proposed, and an iterative solution for calculating tensile strains of a deflected geosynthetic was deduced. In derivation, a virtual inclined slip surface and interaction between the geosynthetic and soil were quantitatively evaluated by coupling the arching effect and the geomembrane effect. Moreover, the development of shear stress along the slip surface can be considered, as well as different segments of the basal reinforcement. Then, the proposed method was validated by two large-scale experiments. Comparison of the results of this method with measurements and results of other analytical models confirmed that this analytical method can take good care of the varying process of the localized sinking, regarding the overlying loads on the geosynthetic and the subsequent tensile strains.

A case of damaging behavior in the concrete lining of an operational railway tunnel is studied and presented in this paper. The study focuses on the influence of tunnel structure damaging due to field observed construction deficiency of cavities around surrounding rocks, which is evaluated by means of field observation and numerical analysis. This work demonstrates that the construction deficiency of cavities around surrounding rocks plays an important role in the stability of tunnel structure, which can vary the stress state distribution of tunnel structure even with damaging behavior. Moreover, the implemented numerical analysis also demonstrates that the damaging behavior of tunnel structure induced by the field investigated cavities can be numerically simulated with taking account of the aforementioned cavities in the numerical model, which provides the design basis for appropriately strengthening the damaged tunnel structure.

To investigate the deformation and damping characteristics of cement treated and expanded polystyrene (EPS) beads mixed lightweight soils, this study conducted a series of triaxial shear tests cyclic loading for different confining pressures, cement contents, and soil categories. Through repeated loading and unloading cycles, axial accumulative strain, resilient modulus, and damping ratio versus axial total strain were analyzed and the mechanical behavior was revealed and interpreted. Results show that the resilient modulus increases with increasing confining pressure and cement content. A decreasing power function can be used to fit the relationship between the resilient modulus and the axial total strain. Although sandy lightweight specimens usually own higher resilient modulus than silty clay lightweight specimens do, the opposite was also found when the axial total strain is larger than 8% with 50 kPa confining pressure and 14% cement content. For damping ratio the EPS beads mixed lightweight soil yields a weak growth trend with increasing axial total strain and a small reduction with higher confining pressure and cement content. For more cementations, the damping ratio of the sandy lightweight soil is always smaller than the silty clay lightweight soil. Nonetheless, the differences of damping ratios that were obtained under all of the test conditions are not significant.

Strain hardening cementitious composite (SHCC) and fiber reinforced mortar (FRM) are considered as suitable for strengthening reinforced concrete (RC) structures, both of which belong to fiber reinforced cementitious composite (FRCC), whereas the distinctive strengthening effects of RC structure using SHCC and FRM have not been sufficiently understood until now. In this study, the comparative study of RC members with flexural strengthening using SHCC and FRM is implemented, focusing on the load carrying capacity and ductility improvement of the strengthened RC member. The result demonstrates that the load carrying capacity of the RC member, even strengthened with a plain SHCC layer, can be improved from that of the RC member with strengthening using a steel-reinforced FRM layer, and the ductility of the RC member with strengthening using a steel-reinforced SHCC layer is significantly improved from that of the RC member with strengthening using plain SHCC layer, because the multiple fine cracks in the SHCC layer are obviously increased even with a low-reinforcement-ratio steel bar adopted in the SHCC layer.

This paper presents a numerical shear stress transfer model for investigating the shear fracture behaviour of strain-hardening cementitious composites (SHCCs) for strengthening reinforced concrete (RC) structures. The model focuses on the transferred shear stress on the crack surface of the SHCC, taking account of the contributions from both the contact stress of the matrix and the bridging stress of the fibres. The numerical results demonstrate that the proposed shear stress transfer model can appropriately evaluate the shear fracture behaviour of SHCCs for RC strengthening, in which the fibre bridging effect on the crack surface of the SHCC has much influence on the shear fracture behaviour of the SHCC strengthening layer.

This paper presents a case study of damage in the concrete lining of an operational tunnel by field investigation and numerical analysis, in which the field-investigated construction deficiency is considered in the numerical model, and the implemented numerical analysis is adopted for investigating the effect of damaging in the structure of the operating tunnel induced by the construction deficiency. The numerical analysis illustrates that the construction deficiency of a cavity can influence the stress state of a tunnel structure and plays an important role in the stability of the operating tunnel, which results in significant influence on the damage in the concrete lining of the operating tunnel and must be timely treated to prevent subsequent damage in the tunnel lining. Moreover, the numerical model considering construction deficiency of a cavity around the tunnel is efficient for evaluating the effect of damaging the structure of the operating tunnel induced by this construction deficiency.

A case of damages in the secondary lining of a multiarch tunnel is studied by field investigation and numerical analysis, which is subject to asymmetry pressure and buried at shallow depth. The study focuses on the key influencing factors inducing these damages. The numerical analysis is implemented, taking account of the possible influencing factors obtained from field investigation, in which two cases with different numerical models are utilized to discriminate the effects caused by shallow tunnel depth and asymmetric pressure on the tunnel comparatively. The numerical result demonstrates that the topography with shallow depth and asymmetry pressure has much influence on the safety of the multiarch tunnel’s structure, and the cause of damages in the multiarch tunnel structure can be analyzed by field investigation and numerical simulation, which can provide the design basis for appropriate strengthening of the damaged tunnel structure.

Strain hardening cementitious composite (SHCC) is an attractive construction material for reinforced concrete (RC) structure strengthening, whereas the behavior of RC member with flexural strengthening using SHCC has not been clearly understood, since it is affected by various complex factors. In this paper, an experimental investigation into failure behavior of RC member with flexural strengthening using SHCC is implemented, which gives initial stage to the broad spectrum of the test. Moreover, a calculation model is also proposed for predicting the load-carrying capacity of flexural strengthened RC member using SHCC, in which the influence of varying SHCC layer thickness is considered. The results demonstrate the cracking behavior of SHCC layer is significantly affected by the varying SHCC layer thickness. The comparison of calculated and experimental results confirms the effectiveness of the proposed calculation model for predicting the load-carrying capacity of flexural strengthened RC member using SHCC.

This paper presents an experimental investigation for evaluating the shear resistance of strain-hardening cementitious composite (SHCC) member. The implemented investigation focuses on the shear fracture characteristics of SHCC member. Especially, the respective contributions of matrix and reinforcing fiber for shear resistance of SHCC member are quantitatively calibrated. The research illustrates that all experimental specimens experience multi-cracking process in the diagonal shear direction. This behavior is significantly influenced by both fiber bridging effect and matrix contact effect, whereas fiber bridging effect gradually plays a dominant role during loading process. Especially, the specimens finally fail in shear due to localization of some multiple fine cracks with losing fiber bridging effect and matrix contact effect on crack surface. Moreover, the quantitative research demonstrates that the shear load carrying capacity of SHCC member can be assumed as the sum of shear load carried by matrix and reinforcing fiber. This work provides an experimental foundation for shear resistance of SHCC member.
