高放核废物处置库T-M耦合数值模拟

考虑到地下工程受地应力、温度、水的相互影响，导致岩体力学性质的改变，采用ANSYS有限元分析软件，基于Mohr-Coulomb破坏准则，建立高放核废物处置库的数值模型，在此基础上进行热-力（TM）耦合二维数值模拟．研究了高放核废物处置库9种方案运行一百年的温度、应力、位移变化，通过对比分析，在满足安全、经济的基础上，选择最佳的处置库间距和深度，为核废物处置库的设计提供参考依据．

Numerical Simulation of Two-Dimension Thermo-Mechanical Coupling in Nuclear Waste Repository

In consideration of the changes in rock mechanics properties result in the interaction effect of stress, temperature and water in underground works, ANSYS finite element analysis software was used based on the Mohr-Coulomb failure criterion, and a numerical model of high-level radioactive nuclear waste（HLW） repository is established. On this basis, a thermal-mechanical （TM） coupling two-dimensional numerical simulation is also conducted. Nine kinds of programs on the HLW repository to run 100 years of temperature, stress and displacement change are studied. By contrastive analysis, to meet the security and economic, the appropriate space and depth of the HLW repository is selected, which could provide a reference for design.
