Numerical analysis of a tunnel in swelling rockmass by a modified Cam-Clay based model

研究成果: Conference contribution

抄録

In the present study, a return mapping algorithm is formulated for an elasto-plastic swell model based on the Modified Cam-Clay(MCC) model, which can show the soft/hard behavior of swelling process by applying the finite element method (FEM). Several simple numerical examples are used to assess the efficiency and convergence of the formulation of the return mapping algorithm. This study is contributed to predicting the nonlinear mechanical response of the tunnel constructed in swelling rockmass, which contains the stress redistribution of the tunnel after excavation and the soft/hard response caused by swelling process. The numerical simulation will show the swell deformation, strain path and stress history of a tunnel which ground masses has occurred the process of water-absorption, aimed at evaluating the stability of a tunnel constructed in swelling rockmass after some years.
