中文摘要：

根据一个典型的热–水–力耦合的线性热弹性固结控制方程,研究无限长圆柱饱和多孔介质在外力和温度耦合作用下的固结问题,给出了温度、孔压、体积应变、径向位移、应变和应力等在Laplace变换域内的表达式,并通过数值逆变换进行求解。利用这一解答,分析了常温度荷载和变温度荷载两种情况下圆柱热固结的演化过程。这一解答可为室内试验结果的分析提供依据。

英文摘要：

A coupled thermo-hydro-mechanical consolidation theory is proposed for a saturated porous cylinder with infinite length.The expressions of the field variations in Laplace transformation space are deduced such as temperature,pore pressure,volumetric strain,radial displacement,strain and stress,etc.Then,the time domain solutions are obtained by a numerical inversion scheme.Using the solutions,the evolution processes of thermal consolidation for a cylinder under axisymmetric conditions are studied for both constant and variable thermal loading conditions.These analytical results can provide some reasonable explanations for experimental results.
