摘要
以核废料贮库裂隙岩体介质热—液—力耗散过程的定解方程为基础 ,结合核废料地下贮存 ,分析了热、液、力三方面的边值及初始条件。根据计算力学加权残值法 ,导出了定解问题的加权积分方程 ,为实现核废料贮库围岩介质 THM耦合有限元数值计算 。
On the basis of the definite equation of thermo-hydro-mechanical coupling in the fractured rock mass surrounding nuclear waste repositories, the boundary and initial conditions in the thermo-hydro-mechanical field are analyzed by the actual case histories. The weighted integral equations of the definite problem are deduced by using the weighted residual method of computing mechanics, which provides a theoretical basis for realizing the numerical computation of thermo-hydro-mechanical coupled FEM in the fractured rock mass media surrounding nuclear waste repositories.
