上海深厚软土分布区超大深基坑工程设计与分析

Design and Analysis of Deep Large Foundation Pits Engineering in Shanghai of Deep Soft-soil Distribution Areas

以上海浦东新区某深基坑工程为案例,主要介绍了深厚软土分布区深大基坑工程的设计要点、深厚淤泥质软土的设计控制措施。项目所在场区淤泥质软土层分布最大厚度约17 m,属于深厚软土分布区。监测结果表明:通过加强基坑施工的过程控制,并在施工过程中采取正确的处理措施,保证了基坑工程的顺利实施,最终达到了的预期效果。

Based on the deep foundation pit project in Pudong New Area,Shanghai,the design points of deep and large foundation pit engineering in the distribution area of deep soft soil,and the design control measures of deep silty soft soil are presented.The maximum thickness of the silty soft soil layer in the project area is about 17 m,which belongs to the deep soft soil distribution area.The monitoring results show that:The foundation pit project was implemented smoothly by strengthening the process control of the foundation pit construction and taking corrective measures during the construction process,and achieved the expected results.
