| 摘 要： | 基于理想模型的假设,将层状结构的非饱和岩体作为研究对象,从等效多相系统的守恒定律出发,建立了非饱和岩体的热流固全耦合模型,这些为研究多孔介质多场耦合提供了一个有效的方法,也为进一步研究温度场—渗流场—应力场耦合问题提供了理论支持,同时对我国垃圾填埋场、路基填土、堤坝防洪、核废料储存等领域工程设计和现场施工均发挥一定的指导意义.

| Abstract: | Based on the idealized model hypothesis,this thesis established thermo-fluid-solid three field coupling model of the unsaturated rock mass from the conservation law of the equivalent multiphase system.Research results provided an effective method for the study of unsaturated porous media coupling problems and do a theory support for further study on coupling problem.Sometimes there was a guiding significance in engineering design and site construction to our country such as landfill,levee and the design and site construction of nuclear waste storage. |

| Keywords: | unsaturated rock mass elastic-plastic model fully coupled thermo-hydro-mechanical model |
