60R2槽型钢轨6号不对称三开道岔设计

为了缓解交通压力,愈来愈多的城市开始大力发展城市轨道交通,如有轨电车、地铁、高架轻轨等。作为轨道系统中薄弱环节的道岔,其设计理念有了新的转变,以适应城市轨道交通所需的特殊道岔的研发。三开道岔是一种特殊的道岔形式,能够减少地下开挖面积,有效降低土建工程造价,节约大量资金,并已应用在城市轨道交通中。本文介绍不对称三开道岔的设计,阐述道岔平面线型、结构设计等关键技术。

Design of No.6 Asymmetric Three-way Turnout with 60R2 Grooved Steel Rail

In order to alleviate the urban traffic pressure,more and more cities begin to vigorously develop urban rail transit,such as tram,subway and elevated light railway and so on.As a weak part of track system,the design concept of turnout has undergone a new transformation to adapt to the research and development of special turnout required by urban rail transit.Three-way turnout is a special type of turnout,which can reduce the underground excavation area and construction costs and has been used for urban rail transit.This paper introduced the design of asymmetric three-way turnout,and expounded the key technologies of the turnout,such as the planar form and the structural design.
