复杂环境下的深基坑内支撑拆除技术

Study on Construction Technology of Deep Foundation Pit Internal Support Removal in Complex Environment

随着城市空间建设的日益发展,超大超深基坑已屡见不鲜,地质情况复杂,基坑形式多变,进而给深基坑围护设计和施工均带来极大的挑战。以南昌正盛太古港商业城项目深基坑内支撑拆除施工为对象,重点研究深基坑内支撑拆除施工方法和安全可靠的控制措施。通过对该问题进行的研究探讨及分析,找到了一种有效的复杂环境深基坑内支撑拆除方法,为其他类似工程的内支撑拆除施工积累经验。

With the development of urban space construction,super large and deep foundation pits have been common,the geological conditions are complex,and the form of foundation pits is variable,which brings great challenges to the design and construction of deep foundation pits. Taking the construction of deep foundation pit support demolition of Zhengsheng Taigugang Commercial City Project in Nanchang as an object,this paper focuses on the construction method of deep foundation pit support demolition and safe and reliable control measures. Through the research,discussion and analysis of this problem,an effective method of deep foundation pit support removal in complex environment is found,which can accumulate experience for other similar projects.
