摘　　要：软土地区的土质性能差、强度低、含水量高,在这类地层中进行深基坑开挖和施工,稍有不当就极易产生险情。以上海市某超大深基坑工程为案例,将软土地区基坑开挖中的变形处置技术和相关经验进行了介绍,并对超大深基坑盆式开挖方法进行了分析与思考,对于同类工程具有一定的借鉴作用。Soil in soft soil area has characteristics of poor performance, low intensity and high water content, so deep foundation pit excavation and construction in such area would easily lead to dangers, even with the tiniest inappropriateness. With a large deep foundation pit in Shanghai as example, the paper introduced the application and relevant experience of controlling pit deformation in soft soil area, and carried out some analysis and introduced some ideas about large basin deep foundation excavation methods, which could be reference for similar projects.
