摘要

采用三维非线性动力有限元方法 ,对甘肃海甸峡水电站的面板堆石坝和高趾墙的动力反应特性进行计算研究 ,详细分析了高趾墙的动力应力变形规律 ,论证了该设计方案高趾墙布置的合理性
At the preliminary design stage, the concrete facing rockfill dam is parallelly arranged together with the concrete overflow gravity dam in one scheme of Haidianxia hydropower station, in which a gravity high-toe wall with the height of nearly 50m is used, which is the highest one in China now. Its stability and safety is the key problem to the project. This paper performs a 3-D FEM dynamic analysis for the concrete facing rockfill dam and the gravity high-toe wall, analyzes its earthquake response in detail, and studies its dynamic working behavior under design earthquake condition. It is proved that the given design scheme is reasonable and feasible.
