【Abstract】 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.更多还原
