土钉墙支护基坑工程的监测与稳定性分析

The Monitoring and Stability Analysis on Soil Nail Wall Supporting Excavation Engineering

通过对土钉墙支护基坑工程中土钉内力的测试和对基坑边坡及边坡附近土体位移的监测,分析土钉内力与基坑开挖深度的关系、不同土层中土钉内力沿土钉深度的分布情况、基坑边坡及附近土体的位移规律,对土钉墙的设计和施工提出一些指导意见。

Based on the test of the internal force on soil nail in soil nail wall supporting excavation engineering and the monitoring of excavation slope and the soil displacement near excavation slope, analyzes the relation of the internal force on soil nail and excavation depth, the distribution of the internal force on soil nail along the depth of soil nail in the different soil layer and the rule of excavation slope and the soil displacement near excavation slope. And it puts forward some guid- ance on the design and construction of soil nail wall.
