摘要
以北京某基坑支护工程为例,通过对现场护坡桩发生较大水平位移的原因进行分析,采取了调整设计,增加锚杆,清除护坡桩与开闭站之间的部分土方,分段开挖及施工等相关措施,有效的控制了护坡桩变形,确保了周围建筑物和基坑支护的安全,为以后类似基坑支护工程发生位移等施工状况提供了相关的解决思路。
Taking a foundation pit support project in Beijing as an example.By analyzing the reasons of the displacement of the slope protection pile,the relevant measures are taken,such as adjusting the design,adding bolts,removing part of the earthwork between the slope protection pile and the building,segmented excavation and construction,which effectively control the deformation of the slope protection pile,and the safety of the surrounding buildings and foundation pit support is ensured,which provides relevant solutions for the displacement of similar foundation pit support engineering in the future.
