Thermal drainage consolidation method is a new technology of soft foundation treatment, which involves the coupling of thermo-hydro-mechanical field, and the action mechanism is complex. In this paper, taking the model test of thermal drainage consolidation as the prototype, the finite element model of thermal drainage consolidation is established by using Abaqus software, then, the numerical results are obtained and are compared with the results of model test, and the reliability of the numerical model is verified. The results show that when the applied load is constant, the higher the temperature is, the faster the consolidation speed of soil is, but with the increase of temperature, the consolidation effect of the same temperature difference will gradually weaken. In addition, the thermal drainage consolidation method can achieve the best treatment effect when the temperature of the soil reaches 60 ℃.

Compaction Method

Along with large national investment in infrastructure construction, the mileage of the highway, which is one of the infrastructures, has increased year by year. There are many kinds of artificial filling foundation treatment methods for housing construction project in mountain highway facilities. This paper, combined with the engineering example, focuses on the dynamic compaction method and the replacement method.

Study on the permeability of three kinds of soil research, including in loess, calcareous-soil, lime and fly ash (two ash) of loess, cement-soil. Selects 10 groups of soil to determine the coefficient of permeability.The results show that: cement-soil of 3:7 can be used as impervious material than calcareous-soil of 3:7. Calcareous-soil of 3:7 can be used as seepage control material in short-term.Two-ash can not play this role; As the same time, we found that: The coefficient of permeability of all kinds of modified soil are increasing after 21 days.
