Seismic Analyses of 3D Fengman Concrete Gravity Dam

Abstract:

In this paper, the new Fengman gravity dam is numerically simulated to study the seismic response and safety evaluation by considering the different strength grade concrete partition, corridor, a discharge hole and gate pier. A complex 3D FEM of a real overflow monolith was built by taking advantage of AutoCADand ANSYS, nonlinear seismic response was studied under earthquake loads. Numerical simulations show that acceleration, displacement and stresses of dam were obtained in a complex 3D FEM under seismic precautionary intensity of 7 degree earthquake loads, results compared with the dam simple models were on the safe side. Fengman dam was still safe under seismic precautionary intensity of 8 degree earthquake loads, so the dam had enough capacity to resist earthquake action. At the same time, it is concluded that 3D dynamic FEM is very important for safety evaluation of concrete gravity dam subjected to the earthquake. The research provides finite element analysis reference works for comprehensive governance and reconstruction of Fengman Hydropower Station.
