摘要
在水工建筑物的抗震设计中,为了得到满足工程要求的地震波,在已有的人工地震波合成研究的基础上,介绍了根据水工标准反应谱合成人工地震波的方法和参变量的选取,以及强度包络函数模型的确定、初始波的修正与改进方法.以溪洛渡拱坝为例,应用该方法合成人工地震波,结果表明该方法具有简单、易于掌握、计算精度高、收敛快等特点.
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.
