摘要： 利用混合物理论,推导出裂隙岩体等效连续介质温度场、渗流场和应力场三场耦合的全耦合数学模型及其控制方程.采用全耦合求解法给出了控制方程的有限元表达式,编制了相应的二维有限元程序.给出的应用算例计算结果较好地反映了渗流、应力及温度场耦合作用下位移、孔隙水压力、温度的变化规律,表明了该计算模型与所开发的数值计算程序是合理和实用的.

Abstract: With the application of continuum theory of mixture,a fully coupled mathematical model and the governing differential equation of the coupled problem of temperature,seepage and stress fields for equivalent continuum media of fissured rock mass are established.A set of fully coupled finite element formulae are obtained by fully coupled methods,and a 2-D finite element program for solving the equation is developed.The calculation results given with calculation example well reveal the varied behaviour of displacement,pore pressure and temperature under coupled action of seepage,stress and temperature,which indicates the mathematical calculation model and numerical program developed are reasonable and practical.
