苏州汇融广场深基坑换撑技术研究

Research on support change technique of deep foundation pit at Huirong Square in Suzhou

结合苏州汇融广场基坑围护工程实例,通过分析工程的实际概况,对基坑围护方案进行了研究,选取了单排钻孔灌注桩加一道混凝土支撑的围护体系方案,并着重对深基坑换撑技术进行了阐述,实践结果表明:钢筋混凝土换撑具有受力效果好、施工简单、无需拆除的施工优点。

Combining with the containment project at Huirong Square in Suzhou,the paper researches the foundation pit containment according to the analysis of projects,selects the single-line drilling bored pile plus a course of concrete support system,illustrates the deep foundation pit support change,and proves by the result that the reinforced concrete has better stress effect,which is easy for construction without demolition.
