摘要
装配式预应力鱼腹梁钢结构支撑技术是基于预应力原理的一种新型的、先进的、绿色环保的深基坑的内支撑结构体系。结合2个装配式预应力鱼腹梁钢结构支撑体系在软土深基坑中应用的工程实例,介绍了基坑围护方案及基坑开挖效果,体现了装配式预应力鱼腹梁钢结构支撑技术具有绿色环保、经济性好、施工周期短等优点,具有较好的综合效益,同时重点探讨了该支撑技术在深厚软土中存在的问题,可供本地区同类工程设计与施工参考。
Support of prefabricated prestressed fish-bellied beam based on the prestressing principle is a new advanced environmental friendly internal support structure system of deep foundation pit.Two application examples of this steel structure support system in deep foundation pit in soft soil are introduced,including pit enclosure schemes and excavation results.The advantages of this support technology are summarized,including environmental friendliness,economical efficiency,short construction period,with comprehensive benefits.The problems of this support structure in deep soft soil are also discussed.Reference for the similar engineering design and construction in the local area are provided.
