摘要

根据初步设计布置方案,对海甸峡面板堆石坝及其高趾墙的工作性态进行三维有限元计算研究,详细分析了高趾墙的变形、应力等工作性态,论证了高趾墙设计方案的合理性。
In the preliminary design stage,one scheme of Haidianxia Hydropower Station is that the concrete facing rockfill dam is parallelly arranged together with the concrete overflow gravity dam,in which a gravity high-toe wall with the height of nearly 50m is used,which is the highest one in China now. The stability and safety of the gravity high-toe wall is the key problem of the project. This paper performs a 3-D FEM calculation for the concrete facing rockfill dam and the gravity high-toe wall,analyzes the deformation and stress distribution of the gravity high-toe wall in detail,and researches the working behavior of gravity high-toe wall under design and check conditions. It is proved that the design scheme is reasonable and feasible.
