摘要
上海浦东国际机场旅客捷运系统将连接新建卫星厅与既有航站楼,为国内首次将地铁A型车应用于机场交通。该工程涉及地上段地下段衔接、既有段新建段衔接、直线段曲线段衔接、盾构段明挖段衔接及下穿飞行区滑行道等多项技术难题。本文将结合这些技术难题,以自动三维激光扫描技术为基础,探究该工程轨道交通系统地下隧道调线调坡测量的技术与方法。
The mass rapid transit system of Shanghai Pudong International Airport will connect the new Satellite Hall Ⅲ with TerminalⅠ and Terminal Ⅱ,which is the first time of using model A metro train in airport traffic in China mainland. This project involves many difficulties such as the connection between ground and underground sections,between finished and constructing sections,between linear and curve sections,between shielding and digging sections,and the underground passing through airport runway. Considering these difficulties,this paper conducts research on the techniques and methods of route and gradient adjustment measurement of underground tunnel of airport mass rapid transit system based on 3 D laser scanning.
