| 摘 要： | 某水电站右岸边坡地质条件复杂。工程边坡开挖过程中,中倾坡外的断层f231剪出口局部被挖除,边坡稳定问题突出。介绍边坡加固设计方案和安全监测布置情况,基于EL.1150m以下三层抗剪洞施工期监测数据,讨论变形与开挖、变形与地质结构的关系。分析结果表明：边坡抗剪洞开挖期间,以f231为底滑面、β4为后缘切割面、β219为上游侧裂面构成的局部块体存在轻微的滑移拉裂变形。边坡继续下挖后,抗剪洞内监测显示有轻微的挤压变形,变形未见异常,基本满足设计要求。

| Abstract: | The geological conditions are complex in the right slope of a hydroolectric project.The stability of right slope is remarkable during constructionn and operation after shear opening of Fault f231 which trends outside came out during excavating.This paper introduces reinforcement design scheme and monitoring design.Safety problem becomes especially important while three shear-resistants are below EL.1150m excavated.Based on the monitoring data of this period,this paper discusses the relationship between defo... |
