【Abstract】 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.更多还原
