逆作法在复杂环境深基坑工程中的应用研究

Study on the Application of Top-down Construction Method in DeepFoundation Pit Engineering in Complex Environment

以上海市中心某深基坑工程为例,阐述了逆作法施工技术在施工场地狭窄、周边建筑密集的深基坑工程应用中的质量控制要点。实践显示,逆作法有效地解决了施工场地狭窄和工期紧张问题,保证了基坑及周边建筑群的安全,可在类似深基坑工程中推广应用。

Taking a deep excavation engineering in the center of Shanghai as an example,the key points of quality control is introduced in the top-down construction in deep excavation with narrow construction site and dense surrounding buildings.Practice shows that the top-down construction technique can effectively solve the problems of narrow construction site and short construction period,ensures the safety of the excavation and surrounding buildings,which can be applied in similar deep excavations.
