摘　　要：对于软土地区深基坑作业来说,施工变形和风险控制是关键。以上海浦东机场内某半逆作的深基坑为背景,通过对基坑监测数据分析,对软土地区深基坑工程的变形性状进行了分析总结。根据该工程基坑的变形性状分析,结合类似软土地区基坑工程的实践经验,从前期设计和施工过程控制两方面提出了一些基坑变形和风险控制要点。研究结果可为类似软土地区深基坑工程的科学施工提供经验借鉴。For deep excavation operations in soft soil areas,construction deformation and risk control are paramount.Based on a semi-reverse deep foundation pit in Shanghai Pudong International Airport,the deformation behavior of deep foundation pit in soft soil area is analyzed and summarized by analyzing the monitoring data.According to the analysis of the deformation behavior of the foundation pit in this project,combined with the practical experience of foundation pit engineering in similar soft soil areas,some key points of foundation pit deformation and risk control are put forward from the aspects of design and construction process control.The research results can provide experience for the scientific construction of deep foundation pit engineering in similar soft soil areas.
