对铁路站场到发线曲线地段建筑限界加宽方法的探讨

Study on Method of Widening Structure Gauge at Curve Section of Railway Arrival-Departure Line

现行规范对铁路站场到发线曲线地段建筑限界加宽方法有相关规定,实际应用中因动车组列车与普速列车基本参数的差异导致曲线地段建筑限界加宽与实际有差距。通过阐述铁路站场设计现行曲线限界加宽的相关规范规定,结合铁路总公司对客站曲线地段建筑限界加宽的最新要求,分析铁路到发线曲线地段建筑限界加宽的理论计算公式,指出现行曲线地段建筑限界加宽规定存在的主要问题,从而修正现行曲线地段建筑限界加宽的相关规定,以满足实际曲线地段建筑限界加宽要求,杜绝运营中发生车体剐蹭建筑物的事故。

Though widening structure gauge at curve section of railway arrival-departure line is specified in the current codes, but the basic parameter differences between CRH train and general speed train cause some difference in the widened structure gauge and the practical requirement. With reference to the latest requirement by China Railways Corporation for the structure gauge widening at the curve section of passenger station, this paper analyses the theoretical calculation formula and points out the present problems of widening structure gauge at curve section of railway station,then proposes amendments to the present codes to meet the practical requirement and prevent the train from touching structures.
