The Synthesis and Correction of Simulated Earthquake Wave
In order to obtain the earthquake waves that satisfied with engineering specification, the method for the synthesis of simulated earthquake wave with time-frequency, based on hydraulic design response spectrum, is introduced in the seismic design of hydraulic structure. Because of the remaining long period components, the integrated displacement data, by double integral of the acceleration history of the simulated earthquake wave,have great baseline shift from the true one. Least square method is used in this paper to simulate average value of the acceleration history. By this method, the shift is corrected. Finally, in connection of actual project of Xiluodu arch dam,the simulated earthquake wave is synthesized and adjusted, the result shows that the method is simple and easy to grasp, has high precision.
