摘要
本工程通过采用MJS及RJP工法对紧邻地铁周边环境基坑围护结构进行微扰动加固,同时对基坑降承压水采用一种RJP工法封底加固替代抽降承压水的新工艺。解决承压水抗突涌稳定问题,可以减少止水帷幕的插入深度,并减少对周边既有设施的扰动。该方法在邻近地铁设施的深基坑工程中取得了良好的实践效果。
This project uses the MJS and RJP methods to micro-disturb-reinforce the retainingstructure of the foundation pit near the subway. At the same time,a new RJP sealing method is adoptedto replace the pressure-bearing water of the foundation pit. Solving the problem of pressure surge resistance to inrush stability can reduce the insertion depth of the water stop curtain and reduce the disturbance to the surrounding existing facilities. The method has achieved good practical results in the deepfoundation pit project near the subway facilities.
