【摘要】 在VII度设防烈度下,按《水工建筑物抗震设计规范》(DL5073—2000)的标准和方法对观音岩碾压混凝土重力坝泄水坝段进行三维有限元动力计算。分析其地震动力响应,泄水坝段坝趾、坝踵及进水口、泄水口的应力、应变状况。计算结果表明,坝体满足抗震设防要求,是安全可靠的。更多还原

【Abstract】 According to the criterions and methods given in Specifications for Seismic Design of Hydraulic structures(DL5073-2000),the dynamic response of Guanyin-yan RCC Gravity Dam is calculated with 3D finite element method under the seismic fortificati-on intensity of 7 degree,Stress and strain of the various parts of the dam.The result indicates that the seismic fortification requirement for the dam can be met an d it is safe and credible.更多还原
