欧标BS EN 15273铁路限界的设计思路与计算原则

Design Orientation and Calculation Principles for Railway Gauges Based on BS EN 15273

研究目的:随着我国"一带一路"倡议的实施,国内企业在海外承担的铁路设计和建设项目越来越多。在国外项目中,由于历史原因,很多国家的轨距及限界均不统一,通常采用的限界标准有国际铁路联盟UIC标准、欧盟EN标准、英国BS标准等,其中BS EN 15273限界标准应用较为广泛。该标准的研究在国内的应用成果不多,本文旨在介绍该标准的基本原理和在铁路工程设计中的应用方法。研究结论:(1)应用范围:适用于新建铁路和改建铁路,不适用于自动导向交通和独轨交通;(2)限界分类:根据限界计算原则和适用范围的不同,分为静态限界、动态限界和动力学限界三种;(3)本文研究可供设计人员在采用BS EN 15273标准的海外铁路工程项目中开展限界设计时参考。

Research purposes:With the development of the Belt and Road Initiative of our country,there are more and more overseas railway projects undertaken by Chinese companies.In most foreign countries especially in south-east Asian countries,railway gauges are not unified.UIC,EN and BS standards are always used for railway gauges design,especially BS EN 15273 standard is commonly applied in overseas railway project.Since there are not many study results for BS EN 15273 in our country,this paper introduces the basic principle and calculation methods of railway gauges.Research conclusions:(1)Scope of application:it is applicable for newly built or updating railway projects,but not for automated guided transit or monorail projects.(2)Classification of gauges:in accordance with the difference of application scope and calculation principle,the railway gauges are classified to static gauge,kinematic gauge and dynamic gauge.(3)This paper can be used as a reference for designers to carry out gauge design in overseas railway engineering projects using BS EN 15273.
