城市轨道交通工程隧道结构断面测量技术方法的实践与探索

Practical Exploration of Tunnel Structure Cross Section Measurement for Urban Rail Transit Engineering

城市轨道交通工程隧道结构断面测量,是验证土建施工后结构断面尺寸和有效净空能否满足设计要求所进行的测量工作。城市轨道交通工程隧道结构断面形式多样、测量点多,要求精度高,其施测方法多种多样,但都有其自身的缺点和局限性。本文以我院在北京、西安、天津、杭州等城市轨道交通工程隧道断面测量工作的实际测量作业为背景,介绍了一种利用全站仪结合VBA程序设计拟合断面测量的方法。

The structure cross section measurement of Urban transit engieering is necessary work to verify that if the structure section size and the effective clearance after the civil construction can meet design requirements.Tunnel structure is various informative,which requires high precision and lots of measuring points.But all survey methods have their own shortcomings and limitations.With Xi＇an,Tianjin,Hangzhou and other urban rail transit tunnel cross-section measurements as the background,the paper introuduces a method of using total station measurement combined with VBA programming fitting.
