摘　　要：文章以某项目深基坑支护结构选型为例,结合工程地质水文条件以及施工进度和成本等综合因素,通过分析基坑主要特点、基坑需主要解决问题,对基坑支护总体方案进行比选,在确保基坑本身及周边环境安全的前提下,分别从整体顺作法、分区顺作法、逆作法三个方面对工期及费用进行综合分析,确定最佳围护体系,确保基坑施工稳定安全。Based on the selection of a deep foundation pit support structure,combined with engineering geological and hydrological conditions,construction progress and cost and other comprehensive factors,through the analysis on the main characteristics of the foundation pit,the main problems to be solved in the foundation pit are determined,and the overall plan of the foundation pit support are selected.On the premise of ensuring the safety of the foundation pit itself and the surrounding environment,the construction period and costs are comprehensively analyzed from three aspects of overall construction method,zoning construction method and reverse construction method so as to determine the best enclosure system,and to guarantee the stability and safety for the construction of foundation pit.

关 键 词：深基坑支护结构 整体顺作法 分区顺作法 降水运营维护期
