supporting rail

On summery of initial supporting construction of transverse gallery of No.5 vertical shaft in Beijing rail underground transit line

北京铁路地下直径线5号竖井横通道初支施工

It is composed of a door-shaped rail hook, an eccentric cam and a supporting plate.

它由门型轨钩 、 偏心凸轮和支撑板三部分组成.

Rail transit in our country is now in a rapidly construction and development period, so the application of supporting block track has a bright future.

目前，我国轨道交通正处于快速建设和发展时期，其应用前景十分广阔。

Research on Dynamic Characteristics of Supporting Block Track on Bridge in Urban Rail Transit

城市轨道交通桥上承轨台式轨道结构动力特性研究

Based on comprehensive investigation and documents, the paper takes the supporting block track as research object, researching its dynamic characteristic from ideas of systemic and an overall consideration of wheel-rail, tract-bridge interaction.

本文在大量的文献调研基础上，以桥上支承块承轨台轨道结构为主要研究对象，从系统的观念出发，综合考虑轮轨相互作用与桥轨相互作用，对其动力特性进行研究。
