普速铁路T梁运架方案比选及适用性探讨

Scheme Comparison and Adaptability Study on T-beam Transportation and Erection in Ordinary-speed Railway

现今普速铁路桥梁上部结构主要以简支预应力混凝土T梁为主。T梁的制运架方案是铁路建设项目施工组织设计的重点内容之一。T梁制运架方案设计决定了制(存)梁场的设置,直接影响了项目总工期及总投资。本文以某普速铁路为例,对我国铁路T梁施工方案中的运输架梁方案的比选及比选方案的适用性进行阐述。

Nowadays,the bridge superstructure of ordinary-speed railway is mainly composed of simply-supported prestressed concrete T-beam.The T-beam fabrication,transportation and erection scheme is one of the key contents of the construction organization design in railway projects.The scheme design determines the setting of beam production(storage)field,which directly affects the total construction period and investment.In this article,an ordinary-speed railway is taken as an example to explain the comparison scheme of beam transportation and erection in railway T-beam construction in China and its adaptability.
