采用多相多类方法,提出热–水–力耦合作用分析的综合模型。分析考虑多孔介质的三相(固、液、气)和三类(矿物、水分、空气)模型,该模型是根据控制方程、本构关系和平衡条件来建立的;并提出用于模拟高放废物地下处置体系附近场地性状的热–水–力耦合分析通用程序。热–水–力耦合分析可将工程屏障中不同过程间发生的主要相互作用,以及附近岩石的散热和水化现象都考虑进去。通过试验结果的验证,得出一些关于热–水–力方面的重要结论。
Using the multi-phase and multi-class method, a comprehensive model of thermo-hydro-mechanical coupling analysis is proposed. The three-phase (solid, liquid, gas) and three (mineral, moisture and air) models of porous media are considered. The model is based on governing equations, constitutive relations and equilibrium conditions. General procedure for thermo - hydro - mechanical coupling analysis of site properties near waste disposal systems. Thermo-hydro-mechanical coupling analysis takes into account the major interactions that occur between different processes in the engineering barrier, as well as the cooling and hydration of nearby rocks. Through the verification of test results, some important conclusions about thermo-hydro-force are obtained.
