摘　　要：为保障铁路运输安全,应严格控制铁路建筑限界尺寸。本文首先介绍了制定铁路建筑限界须考虑的因素、曲线段铁路建筑限界加宽计算方法。然后阐述了铁道建筑限界的测量内容、测量坐标系的建立以及测量原理,对比分析了现用三种铁路建筑限界测量设备的准确度和测量效率,给出了测量设备的量值溯源方法。最后指出了铁路建筑限界测量存在的问题及今后的发展方向。In order to ensure the safety of railway transportation,the size of railway structure gauge should be strictly controlled. Firstly,this paper introduced the factors to be considered in formulating railway structure gauge and the method of widening railway structure gauge in curve section. Then it expounded the measurement content of railway structure gauge,the establishment of measurement coordinate system and measurement principle,compared and analyzed the accuracy and measurement efficiency of three kinds of existing railway structure gauge measurement equipment,and gave the traceability method of measurement equipment. Finally,the existing problems and future development direction of railway structure gauge measurement were pointed out.
