三角高程测量在地下轨道交通工程联系测量中的应用

在地下轨道交通工程建设中,需要通过联系测量的方法把高程传递到地下。本文通过对全站仪三角高程测量的精度分析以及工程实例,介绍了一种采用三角高程测量进行高程联系测量的方法,该方法在地下轨道交通工程高程联系测量中,能够达到传统悬吊钢尺方法的精度,且操作方法简便,占用竖井井口时间短,大大提高了工作效率。

Trigonometric Leveling for Connection Survey of the Underground Rail Transit Project

In the construction of the rail traffic engineering,Need a way to transfer the elevation to the underground.By analysing the accuracy of trigonometric leveling,the paper entries a method to measure the altitude of the underground marks by trigonometric leveling;and the accuracy is as better as the conventional method,otherwise,it has special merits that simplicity of operator,reduction of holding time of the working aven which increasing efficiency.
