大型深基坑工程群施工技术

Analysis of construction technology for large deep foundation pit engineering group

深基坑是一个非常复杂的系统工程,在施工过程中首要任务是确保基坑及周边环境的安全,而多个基坑组成的深基坑工程群,它的施工技术要求往往较单个深基坑将会更加复杂和严格。依托大型深基坑工程群——九星城(九宫格)项目(大小基坑共计14个),通过对设计方案和施工方案的浅要分析,研究总结大型深基坑工程群在设计及施工中的所采取的技术措施,保证基坑群施工过程中的安全,降低对周边环境的影响。

Deep foundation pit is a very complex system engineering,the primary task in the construction process is to ensure the safety of the foundation pit and the surrounding environment,and the deep foundation pit engineering group composed of multiple foundation pits,it's construction technical requirements are often more complex and strict than a single deep foundation pit.Based on the large-scale deep foundation pit group-Jiuxing City(nine squares) project(a total of 14 large and small foundation pits),through the analysis of the design scheme and construction scheme,the technical measures taken in the design and construction of large deep foundation pit group are studied and summarized to ensure the safety of the construction process of the foundation pit group and reduce the impact on the surrounding environment.
