摘要

利用非线性有限元法

对某湿陷性地基上土石坝进行结构分析。计算中考虑了渗流的作用和土石料的湿陷效应。研究表明

较为深厚和软弱的地基上的心墙坝的变形分布较一般土石坝复杂

应力分布也相对不规则。当地基伴有湿陷性时

这种复杂和不规则程度会进一步加剧

进而影响大坝的安全性。因此

在对这类大坝进行设计时

应充分考虑这些不利因素。

Abstract

The nonlinear finite element method is applied to calculate the stress and deformation of a core wall type earth-rockfill dam on collapsible foundation.In the calculation the seepage and collapsible behaviors of soil-rockfill are considered during the first water impounding.The distribution of deformation and stress of the soil-rockfill dam on deep

soft and collapsible foundation will become more difficult than on the general foundation conditions.The disadvantage conditions must be forecasted sufficiently for the designers.
