摘要
通过高承压水裂隙岩体室内土工试验原始热物理参数、冻结钻孔的实际偏斜资料和测温孔的测温数据,利用ANSYS软件对裂隙岩体的物理力学参数进行反演,得到冻结岩体导热系数、比热容的最优参数。并以最优参数为各岩层的物理参数,利用ANSYS软件模拟各岩层的冻结壁厚度。
Based on the original thermophysical parameters of fractured rock with high con- fined water obtained from lab soil tests, the practical deflection data of the freezing borehole and the temperature data from thermornetry hole, the paper uses the ANSYS software to conduct an inversion analysis on the physics-mechanical parameters of the fractured rock, and obtains the op- timal parameters of specific heat capacity and thermal conductivity coefficient of the freezing rock. And taking the optimal parameters as the physical parameters of every stratum, the paper simulates the frozen wall thicknesses of the strata with ANSYS software.
