基于AutoBank的某均质土坝坝坡稳定性分析

Stability analysis of a homogeneous earthdamslope based on AutoBank

本文通过采用AutoBank有限元分析软件,构建均质土坝计算断面模型,并查阅均质土坝原设计资料,采用现场勘探、室内试验等方法获得坝体及坝基各土层岩土体物理力学参数,对均质土坝现状下游坝坡进行了稳定性分析,并针对均质土坝滑坡现状提出加固方案,计算分析大坝加固后下游坝坡的稳定性。分析成果可为同类工程坝坡稳定性分析及加固提供参考。

In this paper,AutoBank finite element analysis software is used to construct the calculation section model of homogeneous earth dam.The physical and mechanical parameters of soil and soil layers of the dam body and foundation were obtained by referring to the original design data,field exploration and laboratory test,and the stability of the downstream slope of the homogeneous earth dam was analyzed.According to the situation of landslide of homogeneous earth dam,the reinforcement scheme is proposed,and the stability of downstream dam slope after dam reinforcement is calculated and analyzed.The analysis results can provide reference for the stability analysis and reinforcement of dam slope in similar projects.
