浅谈深层水泥搅拌桩在基坑支护中的应用

Elementary Discussion on Application of Deep-layer Cement Agitated Pile in Supporting of Foundation Pit

随着城市建设的发展,高层建筑不断增多,使得基坑开挖深度不断加大,基坑支护变得越来越重要。基坑支护不但要做到安全、稳定,为施工创造条件,而且要兼顾合理、经济。其逐渐成为广大设计、施工人员十分关注的技术热点问题。该文结合工程实例,对采用深层水泥搅拌桩做为基坑支护结构进行了探讨,并指出一些施工中需要注意的问题。

With the development of the city construction,the high-floor buildings are continuously increased so that the excavation depth of foundation pit is continuously deepened. The supporting of foundation pit becomes more and more important. The supporting of foundation pit should be not only safe and stable to create the condition of construction,but also give attention to the reasonableness and economy,which gradually becomes the technical hotspot the mass of designers and builders pay the great attention. Combined with the engineering practical example,the article probes into the deep-layer cement agitated pile to be as the supporting structure of foundation pit,and points out the problems required to be for attention in some constructions.
