| Abstract: | On the basis of the former research on the synthesis of simulated earthquake waves,the method to obtain the earthquake wave based on hydraulic standard response spectrum was introduced,which could satisfy the requirement of the engineering specification in aseismic design of hydraulic structures.Some related problems were discussed in detail,including the methods for selection of correlative variables,the determination of intensity envelope function model,and the modification and improvement of initial waves.The application of the method to Xiluodu Arch Dam project shows that the method is simple and easy to be used,and it is of high precision and fast convergence speed. |
