Natural soils of various types have different electrical properties due to the composition, structure, water content, and temperature. In order to investigate the electrical properties of lateritic soil, electrical conductivity experiments have been conducted on a self-developed testing device. Test results show that the electrical conductivity of laterite increases with the increase of water content, degree of saturation and dry density. When the water content is below the optimum water content, the electrical conductivity of soils increases nonlinearly and the variation rate increases dramatically. However, when the water content, degree of saturation, or dry density increases to a certain value, the electrical conductivity tends to be a constant. In addition, soil electrical conductivity increases with the increase of temperature, and it is observed that the electrical conductivity decreases with the increase of the number of wetting–drying cycles.

Due to the formational environment and climatic variability, granite residual soils with grain-size distribution ranging from gravel to clay undergo multiple drying–wetting cycles. The influences of multiple drying–wetting cycles on the soil-water characteristic curve (SWCC) and pore-size distribution (POSD) of undisturbed granite residual soils are investigated using the pressure plate test and nuclear magnetic resonance (NMR) spin-spin relaxation time (T2) distribution measurement, respectively. Results show that the water-retention capacity and air-entry value decrease and pores become more uniform with increasing drying–wetting cycles. After four drying–wetting cycles, the soil reaches a nearly constant state. The POSD change of multiple drying–wetting cycle samples is consistent with the SWCC of the soils. Furthermore, a modified van Genuchten model in terms of cumulative pore volume is used to obtain the best-fit POSD of the drying–wetting cycle samples. The shape and changing tendency of both curves of SWCC and POSD are quite similar and achieved a better correlation. It can be concluded that the SWCC is strongly dependent on the POSD of the soil and NMR T2 relaxometry can be used as an alternative to the assessment of microstructural variation of residual soils subjected to the periodic drying and wetting process.

About Me
Lingwei Kong obtained his BSc degree from Wuhan Institute of Chemical Technology in 1990, Master degree and PhD from Institute of Rock and Soil Mechanics (IRSM), Chinese Academy of Sciences (CAS) in 1993 and 1997, respectively. He was employed by IRSM immediately after his Master degree as an Assistant Engineer, and trained in in-situ testing at Fugro Geotechnical Services (HK) Ltd from October 1994 to April 1995. He obtained the position of professor of IRSM in 2000, worked in Ecole des Ponts ParisTech (ENPC), France as a senior visiting scholar in 2003, and has been vice director of IRSM (2005-2014).
Dr Kong is now Editor-in-Chief of Rock and Soil Mechanics, Vice Editorial Board Chairman of Chinese Journal of Geotechnical Engineering, member of editorial board of Chinese Journal of Solid Mechanics, Journal of Engineering Geology.
Since 1998, he has been principal investigator for 8 projects sponsored by National Natural Science Foundation of China and more than 40 specific projects. His research interests cover unsaturated soil mechanics, soil dynamic, road engineering, slope engineering, etc., currently concentrated on behaviors of problematic soils and disaster prevention in geotechnical engineering, including expansive soil, laterite, granite residual soil, structural clay, gassy sand and rock-soil mixture deposit. He has published more than 260 journal papers and 90 papers in proceedings, 8 books or book chapters.
