浅议高速铁路建筑限界最大宽度的确定

On Determination of the Maximum Width of the High - speed Railway Construction Clearance

以我国高速铁路设计标准为依据。从机车车辆限界、列车运行时的横向偏移、保证列车运行安全的安全预留三个方面。阐述了确定高速铁路建筑限界宽度的影响因素。从保证行车安全出发，分析了高速铁路建筑限界最大宽度的确定机理。论述了曲线上建筑限界加宽的理论和方法。

On the basis of design standard of high speed railway in China, from the locomotive gauge, the train lat- eral shift and safety reservation that ensure the safety of train operation, this paper expounds the influence factors which determine the width of high - speed railway construction clearance. To ensure running safety, it analyzes the mechanism of high - speed railway construction clearance width, and discusses the theory and method of curve con- struetion clearance widening.
