摘　　要：伴随城市化进程和国家产业转型升级的推进,大批污染型企业的搬迁导致城市中出现大量遗留污染场地。各大建筑企业及建设单位在城市建设的过程中,可能会面临前期场地修复程度不理想的情况。依托上海市长宁某地块项目,对于污染环境下的深基坑施工作业,从污染环境下的防护措施、污染水的抽提、土方及支撑施工、基坑风险控制等方面进行阐述,可为后续类似工程提供借鉴。Amid urbanization and national industrial transformation and upgrading,relocation of many polluting enterprises leads to emergence of numerous polluted sites in cities.In urban construction,major construction enterprises and construction units may face situations with insufficient early-stage site remediation.Based on a project in a plot in Changning,Shanghai,construction of deep foundation pit under polluted environment is discussed from aspects of protective measures in polluted environment,polluted water extraction,earthwork and support construction,and foundation pit risk control,which can provide reference for subsequent similar projects.
