摘 要: | 为研究重力坝坝基抗滑稳定性,以含软弱夹层复杂地质条件的重力坝为研究对象进行分析。从刚体极限平衡法出发,对各参数的敏感性进行分析评价,用刚体极限平衡法和ANSYS分析软件分别进行抗滑稳定计算,并进行结果对比。有限单元法与刚体极限平衡法得出的坝基深层抗滑稳定安全系数较为接近。有限单元法能分析各种复杂形状,比刚体极限平衡法更接近于真实状态。

Calculation Methods for Stability Against Sliding of Gravity Dam's Base |
| |
Abstract: | In order to study the stability against sliding of gravity dam's base,the gravity dam with the weak interlayers and complex geologic conditions is adopted as an investigated subject.The limit equilibrium method of rigid body and ANSYS software are applied to analyze and appraise the sensitivity of various parameters,make calculation for the slability against sliding and make comparison for the calculation results.The results show that compared with the limit equilibrium method of rigid body,the finite element method is further in agreement with the actual conditions as it could be used to analyze the various complex forms. |
