深基坑不同支护形式的监测结果对比分析

Analyzing the Monitoring Results of Different Deep Excavation Supporting Forms

以石家庄市某深基坑工程为例,对桩-锚、土钉墙2种支护结构坡顶水平位移进行监测,并做数据分析。对比发现,桩-锚较土钉墙支护效果更佳;2种支护形式都存在基坑的空间效应。

With the rapid development of economy in our country, the development and utilization of under- ground space is becoming more and more popular, as well as the construction of deep foundation pit engi- neering. This paper, we take a deep foundation pit engineering of Shijiazhuang as an example to monitor the top horizontal displacement of the pile anchor supporting and soil nail wall supporting struc- ture. Through the data analysis and comparison, it is obvious that the support ability of pile anchor is much better than the soil nailing wall. Two kinds of supporting forms are all existing the effect of foundation pit space.
