双排桩在武汉地区深基坑支护中的应用探讨

Discussion on Application of Double-row Piles in Deep Foundation Pit Support

武汉地区高层建筑地下室设计为了解决建筑用地紧缺和市中心交通拥挤、停车位不足的问题,市区高层建筑的地下室向大、深方向发展。随之而来的大、深基坑支护结构的技术要求越来越高。双排桩支护结构作为新型的深基坑支护结构形式,近几年开始在武汉地区运用。通过工程实例的成功经验,探讨双排桩在武汉地区深基坑支护中的应用和发展,可供同类工程借鉴。

In order to solve the shortage of building land and traffic congestion, the problem of insufficient parking spaces, the urban high-rise building basements have developed in direction of large size and depth. The growing demand for technology of deep foundation pit support is more and more high. In recent years support structure with double-row piles as a new type of support structure for deep foundation pit has been applied in Wuhan. From some successful experiences of engineering example, the authors discuss the application and development of double-row piles in deep foundation pit support, which give reference to the similar projects.
