Dr. Song Huaibo currently holds a position at the School of Smart City and Transportation / School of Urban Rail Transit, Southwest Jiaotong University. His core research focuses on the reliability of railway infrastructure in complex environments, with an emphasis on energy geostructures. The key direction of his research is "the heat transfer performance of energy geostructures and their thermo-hydro-mechanical (THM) multi-field coupling responses". Through systematic research, he has revealed the interaction mechanism between energy pile and soil interfaces under cyclic thermal loads, established calculation models for the representative temperature changes of energy piles and the long-term coupling responses of single/group piles, and proposed an optimal design method for energy pile sizes that accounts for soil parameter uncertainty—providing critical theoretical and methodological support for the engineering application of energy pile technology. As the first/corresponding author, he has published 11 SCI papers (including 1 highly cited paper) in top-tier journals in the fields of geotechnical engineering and energy, such as *Canadian Geotechnical Journal* and *Renewable Energy*. He also holds 37 authorized invention/utility model patents and software copyrights. In terms of academic interests, he continues to deepen research on the evolution of long-term bearing performance of energy piles in complex scenarios such as seasonal frozen regions and unsaturated soils
