折线台阶状基础面重力坝的抗滑稳定性分析

Anti-sliding Stability Analysis of Gravity Dam with Polyline Stepped Foundation

折线台阶状基础面重力坝的抗滑稳定性分析,目前尚无统一完善的计算方法,基于滑楔法及重力坝深层抗滑稳定分析方法,提出了一种视坝体为刚体、滑动体由若干楔形体组成的简易方法,编制了计算程序,并将其应用于漫湾水电站#4坝段抗滑稳定性分析中。结果表明,该方法简便实用、计算成本低,且精度较高。

At present there is not common and perfect method for anti-sliding stability analysis of gravity dam with polyline stepped foundation.Based on the idea of sliding wedge method and anti-sliding stability analysis of gravity dam,a simple method is put forward and the computer program is developed,which takes the dam body as rigid body and slide mass is made up with wedges.This method is applied to analyze anti-sliding stability of Manwan #4 monolith.The results show that the method is simple and practical with lower computational cost and higher precision.
