| Abstract: | Using MIDAS/GTS nonlinear finite element a- nalysis method, the prestressed anchor flexible retaining system has carried on the numerical analysis, based around the princi- ple of belting and belting way, for the change of displacement of soil under the bolt support, the pit deformation, and simulated the mechanics characteristics of belt axial force and curve fitting. Results show that the right combination of soil parameter, design of belting, play to its bearing capacity, effectively control the deformation. |
