在建立了岩体裂隙介质三场耦合微分控制方程的基础上,推导了岩石、裂隙,水,气三相介质的温度场、变形场、渗流场耦合模型及有限元解析格式和分析计算方法,对国内某煤矿的多孔裂隙介质三场耦合实际工程问题进行了求解,对结果的可靠性及分析精度进行了论证。 Based on the three coupled differential governing equations of rock media, the temperature field, deformation field and seepage field coupling model of rock, fissure, water and gas three-phase media are deduced, and the analytical format and analytical method of finite element are deduced. This paper solves the practical engineering problems of three coupled porous media in a coal mine in China, and demonstrates the reliability and accuracy of the results.
