| 摘 要： | 根据地铁屏蔽门的定位限差进行精度估算,从理论推导和实验两个方面,得出使用高精度全站仪采用不量仪器高和棱镜高的中间设站三角高程测量方法可以满足地铁屏蔽门测量在高程上的精度要求。通过对地铁屏蔽门的门体结构和各种单元的布置位置的研究,提出只要定位滑动门门柱的位置即可定位屏蔽门的一个单元的思路,减少了屏蔽门安装测量的工作量,对屏蔽门安装定位精度也没有影响。本文详细阐述了屏蔽门安装测量的全过程。

| Abstract: | Based on the limited error of the platform screen door installation ,it estimated the surveying precise requirement .According to the theory and the result of experiments ,with the precise total station equipment and fixed prism ,the trigonometric leveling methods could meet the requirement of platform screen door installation .By the study on the structure and unit disposition of the screen door ,it raised the method of fixing the position of slide posts to locate the door ,which reduced the workload without loss of accuracy .This paper described the surveying process of the platform screen doors system . |
