摘要
随着车辆由滑动轴承发展到滚动轴承,车辆单位基本阻力减小,同时列车运行速度提高产生"列车风",车辆更易产生溜逸,从而给铁路安全带来隐患。既有铁路修建不同时期,执行标准不一,车站改建应从投资、工程实施、施工安全、合规性和市场运营管理等多方面综合考虑,确定改建方案的可实施性和车辆防溜的安全措施。本文对某区段站改建方案进行了分析研究,采用设备软化既有站超限坡提高安全性,为既有车站改建防溜问题提供了一种解决思路。
The unit basic resistance of the cars is reduced as the sliding bearing is changed to rolling bearing,and the train running speed is increased,which results in the"train induced air flow"that makes cars prone to roll away,thus posing a safety hazard for the railways.As existing railways are built at different periods of time where different standards are implemented,the reconstruction of stations should be considered from a variety of perspectives such as investment,project implementation,construction safety,compliance and market operation and management,to determine the feasibility of the reconstruction schemes and the safety measures for car rolling away prevention.This paper analyzes and studies the reconstruction scheme of a district station,and provides a solution to the car rolling away prevention problem in station reconstruction,i.e.using the equipment to soften the over-limit slope of the existing station to improve safety.
