摘　　要：铁路车站咽喉区道岔岔心距是铁路车站平面、横断面设计的基础.铁路车站及枢纽设计规范自2017年12月开始执行,道岔号数的选择、道岔计算的规范发生了一定变化.结合规范具体条文,对道岔号数的选择结合车站实例进行分析,将车站咽喉区道岔的岔心距分为对向布置、顺向非平行布置、道岔尾部类平行布置、间接计算4类,根据采用的道岔型号、线间距和道岔参数等条件,结合实例分析比较每种类型道岔的岔心距计算方法,使复杂的岔心距计算更具操作性.The center distance of turnout in throat area of railway station is the basis of plane and cross-section design of railway station.The design code for railway stations and hubs has been implemented since December 2017,and the selection of turnout numbers and the code for turnout calculation have changed to some extent.Combined with the specific provisions of the code,the selection of turnout number was analyzed in combination with the station example.The turnout center distance in the throat area of the station was divided into four categories:opposite arrangement,parallel arrangement in the forward direction,parallel arrangement at the tail of the turnout,and indirect calculation.According to the conditions of turnout type,line spacing and turnout parameters,the calculation methods of turnout center distance of each type of turnout were analyzed and compared with examples,which makes the calculation of complex turnout center distance more operable.
