Using the Finite Element Method Analysis of Tianjin 112 State Line Road Soft Soil Subgrade

Abstract:

By using the finite element method we had studied the Tianjin Expressway Subgrade Settlement.Through the comparison of the reinforcement and the unreinforced two case we studied the principles of strengthening soft soil subgrade and results show that the mixing pile to improve the bearing capacity of the embankment foundation, reduce the settlement of foundation has played a very good role.The finite element method can reflect the nonlinear characteristics of the coupling effect between composite foundation pile, soil and the soil around the pile, the soil using elastoplastic model, and considering the different medium, different distribution,which has great advantages in the analysis of various factors.The finite element method can better reflect the reinforcement of soft soil subgrade.So ,it also can optimize the engineering design.
