Abstract

Abstract

Problems of one-dimensional thermal consolidation of saturated soil under periodic fluctuation of surface temperature were investigated theoretically by establishing the thermal consolidation model. The analytical solutions of excess pore water pressure,temperature increment were deduced by the theory of partial differential equations,and the expressions of settlement were also given. One-dimensional thermal consolidation behaviour of saturated soil was investigated by comparing with the Terzaghi consolidation solution. The results shows that the behaviour of thermal consolidation is affected greatly by the temperature which is embodied by the temperature increase, the rate of heat conduction and period of temperature fluctuation. Under periodic fluctuation of surface temperature,there will be a fluctuation in the behaviour of excess pore-water pressure and settlement in the process of thermal consolidation.
