In this paper, a general interfacial thermal contact model is proposed to investigate the heat conduction characteristics at the interface of bilayered saturated soils. The semianalytical solutions of thermal consolidation of the bilayered saturated soils considering thermo-osmosis effect under ramp-type heating are derived by using the Laplace transform. Then, the expressions of the temperature increment, excess pore water pressure, and displacement are obtained in time domain by using the Crump's method. Comparisons are performed to verify the rationality of the obtained solutions, and the influences of contact transfer coefficient, partition coefficient, and the thermo-osmosis coefficient on the thermal consolidation of the bilayered saturated soil are illustrated and discussed. Neglecting the thermal contact resistance would overestimate the thermal consolidation behavior of the bilayered saturated soils. The calculated excess pore water pressure and displacement considering thermo-osmosis effect are much larger than those without thermo-osmosis effect.

考虑热渗透效应的双层饱和土固结的一般界面热接触模型

在本文中，提出了一种通用的界面热接触模型来研究双层饱和土界面处的热传导特性。利用拉普拉斯变换推导了斜坡加热下考虑热渗透效应的双层饱和土的热固结半解析解。然后，利用Crump方法得到了温度增量、超孔隙水压力和位移的时域表达式。通过对比验证所得解的合理性，阐述和讨论了接触传递系数、分配系数和热渗透系数对双层饱和土热固结的影响。忽略热接触阻力会高估双层饱和土的热固结行为。计算出的考虑热渗透效应的超孔隙水压力和位移远大于不考虑热渗透效应的超孔隙水压力和排量。
