摘　　要：针对因建筑布局需要而导致的不规则复杂深基坑形式,采取了分区分坑施工方式以弱化基坑环境保护等级,确保了基坑施工安全。并通过工程施工实际,对该种基坑形式下如何组织土方开挖、结构施工、支撑及隔离桩拆除等施工环节进行了有益的探讨。As to the irregular and complex deep foundation pit form caused by the architectural layout,the construction method of partition and division is adopted to weaken the environmental protection grade of the foundation pit and ensure the safety of the foundation pit construction.Through the practice of engineering construction,some useful discussions are made in this paper on how to organize earthwork excavation,the structure construction,the support and isolation pile demolition and other construction procedures under this kind of foundation pit form.
