铁路单开道岔定位测量的一种新方法

A New Method of Railway Single Turnout Positioning Measuring

简述了一种铁路单开道岔定位测量新方法的原理,以我国铁路12号单开道岔为工程案例,详细描述了铁路单开道岔定位测量主要尺寸的计算方法,说明了单开道岔定位测量的主要步骤与方法。通过实践表明:这种道岔定位测量新方法测量速度是原方法的3～5倍,精度符合《新建铁路工程测量规范》[1]要求,使用的测量工具简单,可供相关工程技术人员参考和应用。

This paper briefly introduces the principle of a new method of railway single turnout positioning measurement. Taking railroad No. 12 single turnout of our country for example, it gives a detailed description of the railway single turnout positioning measuring method for the calculation size and its main steps and methods.The practice shows that the speed of the new railway turnout positioning measuring method is 3 to 5 times of the original method, which can meet the requirements of Regulation for New Built Railway Engineering Survey. The measurement tools are easy to get and it is available for related engineering and technical personnel for reference and application.
