摘要
针对某海外工程项目,采用谱分析法对重力坝的挡水坝段进行二维动力响应分析。计算中分别采用中国规范与美国规范,将计算结果进行对比。结果表明,采用美国规范所得坝体各阶振型频率小于中国规范,而位移及应力极值要高于中国规范。
Aiming at one overseas project, the spectrum analysis method is applied to analyze the 2D dynamic response of the retaining section of the gravity dam. In the computation, both Chinese and American codes are utilized respectively as well as the computing re- suits are compared. The comparison results show that the frequencies of various modes of the dam by American code are smaller than those by Chinese code. But maximum displacement and stress by American code are higher than those by Chinese code.
