摘　　要：随着盾构法隧道施工技术的发展和众多问题的解决,错台引起的管片开裂、拼装困难和防水隐患等问题对施工和运营的影响开始凸显出来。研究者以上海轨道交通二号线西延段为背景,开创性地提出了一种简单直接可行的测量管片错台的方法——百分表-角钢片测距法。用该法采集的数据能很好地反映管片错台发生发展的规律,对错台的深入研究和施工控制具有深远的实践意义。With the development of shield tunnel technique and the solution of many problems,the problems of segment cracking,assembling difficulties and waterproof trouble caused by the dislocation more seriously affect the construction and operation.Taking the west extending section of Shanghai Metro Line 2 as the background,a simple,direct and feasible method-dial-angle sheet distance measurement method is innovatively proposed to measure the segment dislocation.The data collected by this method can reflect the developmental rule of segment dislocation better,which has the far-reaching practical significance for the in-depth study and construction control of dislocation.
