城市轨道交通工程隧道结构断面测量技术

Sectional Survey Technology of Tunnel Structure in Urban Rail Transit

随着城市建设快速发展,轨道交通占据城市发展中非常重要的位置,地下隧道结构形式的相关设计属于城市轨道交通最佳的方案,控制好隧道结构并且进行断面测量非常重要,结构断面测量工作主要是为了印证土建施工整体结构断面的尺寸与净空是否能够满足设计的需求。城市交通轨道工程隧道的整体结构的断面种类繁多以及测量时存在的困难点,对于测量工程隧道断面技术的精准度要求较高,其施工测量的手段也非常多,样式虽多但是自身也有缺陷与局限性。主要阐述城市交通轨道工程隧道整体结构断面实施的测量工作,介绍通过全站仪与VBA程序相结合设计拟定出的测量断面的有效方法。

With the rapid development of urban construction, rail transportation occupies a very important position in urban development.The related design of underground tunnel structure belongs to the best scheme of urban rail transit.It is very important to control the tunnel structure and measure the cross section.The main purpose of the survey is to confirm whether the size and clearance of the overall structural section of the civil construction can meet the design requirements.Traffic in the city of the tunnel the overall structure of the tunnel cross-section of a wide range of measurement and the difficulties encountered in the measurement of the tunnel section of the technical requirements of the higher precision, the construction of the means of measurement is also very much, although many of the style there are also flaws and limitations.This paper mainly introduces the measurement work of the whole section of the tunnel structure of the urban traffic track project, and briefly introduces the effective method of designing the cross section by combining the total station and the VBA program.
