Contact Simulation of CFRD Based on Nonlinear Contact Friction Coefficient

Abstract:

In this paper the direct constraint model is adopt to solve the penetration problem of traditional Goodman element. A method to determine the nonlinear friction coefficient of contact surface between the face slab and cushion of CFRD is proposed. The CFRD of a pumped storage power station is studied using traditional method and method proposed in this paper. Analysis results show that the method proposed in this paper to simulate the contact problem of CFRD is reasonable and more superior to traditional methods.
