昆明柴石滩水库溢洪道高边坡稳定性有限元分析

Finite-analysis of Spillway High-slope Stability of Caishitang Reservoir in Kunming

基于有限元的基本理论,通过对边坡坡体内岩体不同部分的模拟及建立概化地质模型,对边坡坡体应力、位移及其稳定系数进行了计算.分析表明:边坡分级开挖、级间设平台的工程措施合理有效,但由于岩体软弱,仅采取削坡减载措施尚不足以从根本上解决该边坡的稳定性问题.

Based on the basic theory of finite-element,different parts of complicated rock are simulated and the general geologic model is established.Its stresses,displacements and stability factors have been calculated.By systematically analyzing these data,it is showed that engineering measures are reasonable and effective,but these measures can't solve its stability problem basically because of its soft rock.
