摘要
基于动力拱梁法理论,借助GDP32X软件在拱坝体形优化过程中进行敏感性设计,引入了GRUD系数以计算拱坝的动力反应,直接应用地震动加速度波及快速傅里叶变换解算拱坝动力方程,并以松塔拱坝为例进行了实例验证。结果表明,本文方法科学、合理、实用、有效。
Based on the theory of dynamic arch-cantilever method, GDP32X software is applied to sensitivity deslgn of shape lines optimization of arch dam. Dynamic response of arch dam is calculated with GRUD coefficient. And then, seismic dynamic acceleration wave and fast Fourier transform technique is used to solve dynamic equations of arch dam. Taking Songta arch dam for an example, the results show that the proposed method is scientific, reasonable, practical and effective.
