软土地区超大面积无支撑深基坑工程围护设计与监测分析

随着上海城市的发展,市政污水处理工程大规模的建设,为上海城市的污水处理提供支撑.在污水处理工程基坑围护设计、监测中,因基坑无支撑、超大面积开挖的典型特性,围护体变形较大时会引起邻近周围环境的影响甚至危害.在大面积、无支撑深基坑工程施工中的设计及监测总结尤为必要,为后续相似工程提供借鉴.

Retaining Design and Monitoring Analysis of Large Area No-support Deep Foundation Pit Engineering in Soft Soil Area

With the urban development of Shanghai, the large-scale construction of municipal wastewater treatment projects provides the support for the urban wastewater treatment of Shanghai. In the retaining design and monitoring of foundation pits in the wastewater treatment projects, the typical characteristics of large area excavation of foundation pit without support will cause the influence and even harm to the adjacent surroundings during the larger deformation of retaining body. It is necessary to summarize the design and monitor in the construction of large-area and no-support deep foundation pit projects, which can be referred for the follow-up similar projects.
