摘　　要：针对位于城市中心繁华区域、紧邻地铁、地质条件差、地下管线破损严重等复杂环境条件下的深基坑工程,通过合理选用基坑围护体系、施工时对整个基坑合理分区并采用有效的降排水措施,既确保了施工质量,同时又极大地提高了出土效率,有效减少了基坑的暴露时间,从而确保了基坑施工和使用的安全。The foundation pit support system should be properly selected in view of its complex environments, such as .in location of prosperous downtown area and adjacent to subway, in poor geological conditions with seriously damaged underground pipelines. During construction, the whole foundation pit should be divided reasonably with effective dewatering measures, which not only can ensure the construction quality, but also can greatly improve the unearthed efficiency and efficiently reduce the exposure time of foundation pit, so as to ensure the safety in the process of construction and usage.
