深基坑支护在高层建筑基础施工中的应用较多,主要起着支挡保护等作用。本文基于大量的文献资料,对建筑工程深基坑支护工程特点、施工要求等进行了简要分析。然后,分析了建筑工程深基坑支护常用施工技术,包括钢板桩支护技术、土钉墙支护技术、排桩支护技术、深层搅拌桩支护技术等,仅供参考借鉴。 Deep foundation pit support in the high-rise building foundation construction more applications, mainly plays the role of retaining support. Based on a large number of documents, this paper briefly analyzes the features and construction requirements of deep foundation pit support engineering. Then, the common construction techniques of deep foundation pit support for construction engineering are analyzed, including the technology of steel sheet pile support, soil nailing wall support technology, row pile supporting technology and deep mixing pile supporting technology, which are for reference only.
