摘要
中国地震区域的分布十分广泛,在多震地区对面板坝的抗震设计要求很高,文章结合实际工程建立三维有限元模型,在静力分析基础上进行面板堆石坝的动力分析计算,分析混凝土面板堆石坝在设计地震作用下的动力响应,确定大坝的安全稳定性,结论对面板堆石坝的设计优化有一定指导价值。
The seismic region of our country is very widely distributed in China,and the seismic design of the face dam is very demanding in the multi-seismic area.In this paper,a three-dimensional finite element model is established based on practical engineering,and the dynamic analysis and calculation of the face rockfill dam are carried out on the basis of static analysis to analyze the dynamic response of concrete face rockfill dam under the action of design earthquake,and to determine the safety stability of the dam,the conclusions has some guiding value for the design and optimization of the face rockfill dam.
