大园包崩滑体前缘变形及稳定性分析

Dayuanbao Rock Rupture Deformation Monitoring and Stability Analysis

嘉陵江亭子口大园包崩滑体前缘在上部堆载作用下局部出现了明显变形,通过分析堆载过程和监测数据,总结了滑体前缘变形原因及规律,复核了锚拉挡墙的稳定性。稳定性复核和长期跟踪监测表明,大园包崩滑体前缘经二次加固后在设计堆载作用下是稳定的。

The front face of the Dayuanbao rock rupture body has an obvious deformation due to the localized surcharge. Throughout the analysis of the surcharge process and the displacement monitoring, the deformation of the rock mass was sum marized. The stability of the rock anchors is also reevaluated. Based on the long term monitoring and the reevaluation results, it is concluded that rock mass is stable under the design surcharge load.
