关于矩形顶管法施工地铁出入口始发、接收方式的研究及案例分析

随着地下空间的开发利用,矩形顶管工法在地下工程施工中的应用逐渐广泛,出现了多种不同类型的矩形顶管施工案例,特别在地铁出入口施工中.通过对国内既有施工案例的介绍,研究分析了地铁出入口采用矩形顶管法施工时始发、接收方式的特点,结合施工工况等影响因素,总结了目前矩形顶管法施工地铁出入口始发、接收方式及设计原则.在地下过街通道、地铁出入口、商场出入口等设计施工时,该始发、接收方式的设计原则、施工技术可为工程技术人员今后类似工程设计、施工提供参考依据.

Study and Analysis on Starting and Receiving Modes of Rectangular Pipe Jacking in Construction of Metro Entrance and Exit

With the development and utilization of underground space, the rectangular pipe jacking method has been widely used in underground engineering construction, and a variety of rectangular pipe jacking construction cases under different working conditions have appeared. By introducing the existing cases of rectangular pipe jacking projects in subway entrances and exits in China, the characteristics of projects are studied and analyzed and combining with the influential factors to be considered, the origin and reception mode and design principles of the metro entrances and exits under the rectangular pipe jacking construction are summarized. It can be taken as a reference for the design and construction of the rectangular pipe jacking method adopted in underground passage,metro and underground mall of the entrances and exits.
