本文对某一双曲薄拱坝(厚高比为0.179)用ADAP-CH84程序在空库情况下进行了动力计算,得出前16阶自振频率、振型及振型参与系数;并用规范(SDJ10-78)中标准反应谱求得三个地震方向的各自组合位移和组合地震应力。本文还将动力计算结果同模型试验结果作了对比分析,对双曲薄拱坝的自振特性和地震反应提出一些合理的论点。 In this paper, a hyperbolic thin-arch dam with a height-to-thickness ratio of 0.179 was dynamically calculated using the ADAP-CH84 program under empty storage conditions, and the first 16 natural frequencies, mode shapes and modal participation factors were obtained. -78) standard response spectrum in the three seismic directions of the respective combination of displacement and combined seismic stress. In this paper, the dynamic calculation results are also compared with the model test results, and some reasonable arguments are put forward for the self-vibration characteristics and seismic response of hyperbolic thin-arch dam.
