复杂环境下建筑深基坑支护施工技术研究

Research on Construction Technology of Deep Foundation Pit Support in Complex Environment

深基坑指的是开挖深度超过5m,或者深度未超过5m,但现场地下管线、四周环境及地质条件复杂的基坑项目。因此,建筑深基坑项目中时常会面对复杂的地形环境,为有效应对复杂的地形环境,保障深基坑项目安全高效施工,支护施工是关键。基于此,文章以某学校项目深基坑开挖为例,介绍分析了复杂地形环境下多种桩型组合支护体系施工的特点及要点,旨在为类似深基坑项目施工积累经验。

Deep foundation pit refers to foundation pit project with the excavation depth of more than 5m,or not more than 5m,but the site underground pipeline,surrounding environment and geological conditions of which are complex.Therefore,the complex terrain environment is often present in the construction of deep foundation pit projects.In order to effectively cope with the complex terrain environment and to ensure the safe and efficient construction of deep foundation pit projects,supporting construction is the key.Based on this,this paper takes the excavation of the deep foundation pit of a school project as an example,introduces and analyzes the characteristics and key points for the construction of a variety of pile type combined support system under complex terrain environment,in order to accumulate experience for the construction of similar deep foundation pit projects.
