Lining-soil systems are always designed to apply in the severe environment, including high temperature and impact loads. In this work, the thermo-hydro-mechanical responses of a lining-soil system are implemented under a sudden heating. To distinguish from previous works, the thermal contact resistance and the partition coefficient at the interface are considered. And the lining material is regarded as a continuous medium and the surrounding soil as a saturated porous medium. In the numerical part, the closed-form solutions pertaining to temperature, displacement, radial stress and pore water pressure are derived utilizing the Laplace transformation technique and its numerical inversion method. The rationality of the method is verified by comparison, and the effects of the thermal contact resistance, the partition coefficient, interfacial contact models and lining materials on each physical field are discussed. The results indicate that interfacial conditions have a significant impact on the heat transfer process of the lining-soil system.
