| Abstract: | The paper introduces the general situation of the design of tunnel type anchorage of Yichang Bank of Siduhe Suspension Bridge. And on the rock body parameters comprehensively determined by actual measurement, it is simulated all the procedures such as substructure highway tunnel construction, excavation, concreting of tunnel anchorage, prestressed forcing and traveling carriage etc. by three-dimensional elastic and plastic finite element method. And through data overloading it analyzes the structural performance of tunnel anchorage and stability of enclosing rock to provide reliable base for the design of tunnel anchorage of suspension bridge. |
