摘要

某高混凝土面板堆石坝坝基覆盖层深度达45～100 m。应用非线性有限元方法

建立了不同设计方案的三维有限元模型

并详细模拟了坝体填筑施工过程和蓄水过程

比较了不同设计方案蓄水期面板的变形和应力的分布规律

以及面板缝、周边缝及其他接缝的变形。结果表明

将混凝土面板堆石坝面板附近的覆盖层部分开挖

让趾板直接坐落在基岩上

有利于改善面板的变形和应力

有利于减小面板缝、周边缝及其他接缝的变形。

Abstract

The depth of the dam foundation overburden of a high concrete face rockfill dam（CFRD）.The FEM models are setted up for two different design plans.By use of the 3-D nonlinear FEM

the process of construction and impound is simulated in detail

and the behavior of the deformation and stress of the concrete face during impounding are analyzed.It is shown that excavating the overburden near the concrete face of the CFRD and letting the toe slab locate on the bedrock directly can improve the condition of the deformation and stress of the concrete face.
