土建基础工程中深基坑支护施工技术研究

Research on Construction Technology of Deep Excavation Support in Civil Foundation Engineering

随着我国经济建设的快速发展,城市土地资源用地紧张已成为现代化城市建设中极为突出的尖锐问题。因此在开展空间规划与建设中,设计单位应强化对土建工程中地下空间的利用。而深化基础工程的支护施工技术研究,能够更好地满足基坑工程以及地下空间的应用要求。对此本文对基础工程中深基坑支护技术进行案例探究与分析,首先综述了工程基本情况,其次分析了基坑(槽)开挖施工技术与分项工程施工的技术要点,并依据方案设计、方案优化原理与施工组织流程明确了深基坑支护施工工艺流程。本文的研究内容为一线的工程施工优化提供参考和借鉴。

With the rapid development of China's economic construction,the shortage of urban land resources has become an extremely prominent and acute problem in modern urban construction.Therefore,in carrying out spatial planning and construction,design units should strengthen the utilization of underground space in civil engineering.Deepening the research on support construction technology in basic engineering can better meet the application requirements of foundation pit engineering and underground space.This article conducts a case study and analysis of deep foundation pit support technology in basic engineering.Firstly,the basic situation of the project is summarized.Secondly,the technical points of excavation construction technology and sub project construction of foundation pits(trenches)are analyzed.Based on the principles of scheme design,scheme optimization,and construction organization process,the construction process of deep foundation pit support is clarified.The research content of this article provides reference and inspiration for the optimization of frontline engineering construction.
