基于站台安全间隙的城际铁路曲线车站最小曲线半径研究

TB 10623-2014《城际铁路设计规范》中对车站站台与车门的最大安全间隙缺乏明确规定,并且没有从保障站台安全间隙的需求出发对曲线车站最小半径做出规定,不便于指导曲线车站设计。本文基于对车辆基本限界、曲线地段各项加宽因素的综合分析,并结合相关规范对站台安全间隙限值的规定,研究了城际铁路曲线车站站台安全间隙,提出了站台安全间隙建议值;基于站台安全间隙要求,给出了不同类型曲线车站的最小曲线半径的建议值。研究成果对城际铁路曲线车站曲线半径选型、站型设计具有一定的指导作用。

Research on Minimum Curve Radius in Intercity Railway Curve Station Area Considering Platform Safety Gap

In TB 10623-2014 Code for Design of Intercity Railway ,the maximum safety gap between station platform and door is not specif ied and the minimum radius of the curve station is not stipulated according to the requirement of platform safety gap,so the code is not convenient for guiding the design of the curve station.The platform safety gap of intercity railway curve station was studied and the recommended value of platform safety gap was put forward in this paper based on the comprehensive analysis of the basic vehicle gauge and the widening factors in the curve section as well as the stipulation of the safety gap limit of the platform in the relevant codes.The recommended values of minimum curve radiuses for different types of curve stations were given based on the requirement of platform safety gap.The research results can be used to guiding the selection of curve radius and the design of station type of intercity railway curve station.
