摘要
目前应用于重庆轻轨较新线二期工程中的连续轨道梁为简支变连续轨道梁,解决了在采用非承拉式的普通盆式橡胶支座的前提下,以大跨径轨道梁跨越路口的问题。从结构体系(包括主梁、横梁、支座等)探讨了跨坐式单轨简支变连续轨道梁设计和施工的主要特点。采用简支变连续的施工方法,可有效控制轨道梁的线形,降低施工对环境的影响。
This paper introduces a solution for the large-span continuous railway beam,which crosses roads by the common non-tension-resist and basin-shaped rubber support,and the beam is used in the second phase of the straddle type monorail project in Chongqing City.This paper focuses on the structure of the continuous railway beam,discusses its technique characteristies,and argues this technology will effectively control the alignment of railway beam and decrease the influence of engineering over the environment.
