岩土工程深基坑支护施工技术措施研究

Study on the Support Construction Technology of Deep Foundation Pit in Geotechnical Engineering

近年来,随着岩土工程深层坑技术的不断发展,深层坑支护施工技术向受力结构与水结构结合、基坑开挖方式与支护结构形式结合、临时支护结构与永久支护结构结合的综合方式发展,其作为工程建设中最为核心的环节,直接关系着建筑物安全性,在施工中存在较大影响,如何有效解决该环节上存在的施工问题,一直是专家组讨论研究的对象。以下根据我国现状,简要分析深基坑支护存在的问题,并总结相应的调整措施。

In recent years,with the continuous development of deep pit technology in geotechnical engineering,the construction technology of deep pit support develops to the comprehensive mode of combination of stress structure and water structure,the combination of foundation pit excavation mode and support structure form,and the combination of temporary support structure and permanent support structure.As the core link in engineering construction,it is directly related to the safety of buildings and has a great impact in the construction.How to effectively solve the construction problems in this link has been the object of discussion and research of the expert group.According to the current situation of our country,this paper briefly analyzes the existing problems of deep foundation pit support,and summarizes the corresponding adjustment measures.
