正交各向异性岩体热‒力耦合行为的半解析解
A Semi-Analytical Solution for Coupled Thermo-Mechanical Behaviors of Cross-Anisotropic Geotechnical Media
摘要
Abstract
To address the thermal-mechanical behaviors of geotechnical media in engineering including energy piles and geothermal power generation,the governing equations covering the anisotropy of moduli,linear thermal expansion coefficients and thermal conductivity are introduced.Then,the partial differential equations are discretized along depth and time domain based on the discretization rules of the transformed differential quadrature method(TDQM).Various load forms of mechanical loads,heat sources and temperature loads are considered,and the coupled thermal-mechanical solution is obtained after introducing the internal continuity conditions and boundary conditions.The proposed theory is verified through case studies.Finally,a sensitivity analysis is performed to provide a basis for the analysis of thermal-mechanical coupling behavior of layered cross-anisotropic media.关键词
