摘要
装配式预应力鱼腹梁钢支撑是一种新型深基坑支护内支撑结构体系,绿色环保,可回收利用,通过预应力可形成较大挖土空间,并能够有效控制基坑变形。以上海某超大深基坑工程为案例,介绍装配式预应力鱼腹梁钢支撑在深大基坑工程的应用及实施效果。现场实际监测结果显示,装配式预应力鱼腹梁钢支撑在软土地区深大基坑工程中实施效果良好,在工程安全控制和经济效益等方面效果显著,可为同类基坑工程提供参考。
Assembled prestressed fish-belly beam steel support is a new type of support structure system for deep foundation pit,which is green and recyclable.It can form a large excavation space and effectively control the deformation of foundation pit.Taking a foundation pit project in Shanghai as an example,the application and implementation effect of assembled prestressed fish-belly beam steel support in deep and large foundation pit engineering are introduced.The monitoring results show that the prefabricated prestressed fish belly beam steel support has a good effect in deep and large foundation pit engineering in soft soil area,and has remarkable effect in engineering safety control and economic benefits,which can be used as a reference for similar foundation pit engineering.
