| 摘 要： | 根据岩体三场耦合的机理分析,从线性动量守恒、质量守恒和能量守恒出发,理论上推导出以位移、孔隙压力和温度为未知量的THM耦合控制方程组,包括岩块变形场方程、地下水连续性方程和水、岩能量守恒方程.方程组不仅考虑了水、岩的密度随温度和压力变化,同时也考虑了水、岩温度不同具有热交换,最后还对后继研究提出了建议.

| Abstract: | The THM (temperature field—seepage field—deformation field) coupling governing equations,including the deformation equation of rock block,the continuity equation of groundwater and the energy conservation equation of groundwater and rock,are theoretically derived according to linear momentum conservation,mass conservation and energy conservation.In these equations,displacement,pore pressure and temperature are unknown quantities,and not only the variations of the groundwater and rock densities with temperature and pressure but also the heat exchange between groundwater and rock are considered.Finally,some suggestions are proposed for further study. |
