基于信息化施工的超深基坑变形规律的研究

Study on Deformation law of Super Deep Foundation Pit Based on Informatization Construction

以河南省郑机城际铁路明挖法隧道深基坑工程为依托,对明挖法隧道深基坑变形规律进行了研究,为后续及类似基坑工程施工提供了重要依据。主要内容和结论如下:1)对明挖法隧道深基坑工程的变形机理及破坏模式进行了分析。2)结合现场监测数据,对基坑施工过程中支护体系的变形规律和受力特征进行了研究。

This paper takes Henan province Zhengji inter-city railway open excavation tunnel of deep foundation pit engineering as the basis, the deformation regularity of open excavation tunnel deep foundation pit engineering were studied, which provide important basis for follow-up and similar foundation pit engineering construction. The main contents and conclusions are as follows:(1) Analyzing the deformation mechanism and failure mode of open cut tunnel deep foundation pit engineering.(2) Combining with field monitoring data, the deformation law and the stress characteristics of foundation pit construction process and supporting system deformation is studied.
