Environmental geomechanics is the key discipline for solving geoenvironmental problems that have complex interactions between mechanics, physics and chemistry, which profoundly influences the modelling of geomaterial behaviour. The underlying theme of the Discovery Grant relates to Thermo- Hydro- Mechanical-Chemical(THMC) coupling in materials and focuses on the following: (i) Chemical interfaces and their influence on the mechanics and integrity of geosynthetic barriers used in waste containment, (iii) THMC processes in geomaterials susceptible to chemical damage with applications to geologic storage of CO2, and (iii) Coupled THM processes in porous rocks with special reference to heat-induced hydraulic hysteresis in the

环境地质力学是解决地质环境问题的关键学科，它具有复杂的力学、物理和化学相互作用，深刻地影响着地质材料行为的模拟。发现补助金的基本主题与材料中的热-水-机械-化学（THMC）耦合有关，并侧重于以下方面：（一）化学界面及其对废物封隔中使用的土工合成屏障的力学和完整性的影响，和（iii）多孔岩石中的耦合THM过程，特别是热致水力滞后，
