摘要
西龙池抽水蓄能电站的下水库大坝为沥青混凝土面板堆石坝 ,坝址碎石料覆盖层较深 ,且河床基岩面向下游倾斜 ,大坝设计中如何合理利用坝基覆盖层碎石料并减少坝基开挖量是十分重要的问题。本文采用清华非线性解耦K G模型 ,进行大坝三维非线性有限元分析 ,研究了蓄水期坝体变形特点及下游边坡及坝趾区坝基的稳定问题 。
The lower dam of Xilongchi pump storage hydroplant is a bitumen concrete face and rockfill dam. The diluvial coverage is thick in the site and the bedrock surface in the riverbed is inclined toward downstream. It is an important program concerning how to rationally reduce the excavation volume of overburden under the dam. The Tsinghua Nonlinear K G Model is used in the three dimensional nonlinear FEM analysis in this paper. The stress and deformation characteristics of dam and some optimized engineering measures are studied.
