摘要

糯扎渡水电站位于云南省思茅市境内

是澜沧江流域开发中具有十分重要意义的工程。设计土石坝方案的溢洪道开挖边坡的稳定性关系到该方案的合理选择。通过对溢洪道附近的平硐与露头的野外调查

获得了1400余条结构面的详细信息

在岩体结构面统计基础上

运用随机网络模拟的方法得到了溢洪道开挖边坡的裂隙网络图像

分析了岩体结构面的连通率

采用Hoek和Brown提出的GSI体系

对岩体质量进行综合定量评价

在此基础上

提出各高边坡岩体力学参数的综合指标。应用模拟退火算法

搜索出边坡潜在的最危险滑裂面的位置

并运用Sarma法分析了开挖边坡的稳定性

提出各个边坡稳定性的分析评价成果以及建议的边坡系统锚固措施。

Abstract

Nuozhadu dam project is situated in Yunnan province in China

it is the important project in Lanchangjiang river development. The stability of excavated slope of the spillway is the major problem in dam construction. Based on field investigation of the structure of the slope

more than 1400 joints were collected

then

by using the Monte-Carlo simulation method and GSI method

the persistence of the joints and the shear strength index of the slope rock mass were calculated. Furthermore

according to the simulated annealing method

the sliding surface of the slope was determined

the stability of the slope was calculated via improved two dimensional Sarma’s limit equilibrium method. Finally

the method to improve the slope stability was suggested.
