带状工程平面位移监测技术方法的探讨

随着中国城市化进程的推进,城市人口激增,促使城市建设迅猛发展,特别是地铁工程建设的飞速发展,迫使工期急剧缩短。这对地铁工程的施工安全提出了新的挑战。近几年来,在各地加快地铁建设的同时,期间出现的事故相应增多,随着地面塌落、冒顶、透水等问题的出现,给建设单位、施工人员带来了巨大的安全隐患。本文结合近年来地铁的施工监测工作,介绍一种新的平面位移监测方法,对带状工程(长基坑或者U型槽)的平面位移监测方法进行探讨。

The Discussion of The Monitoring Technical and Method in Belt-shape Projects

With development of urbanization,people living in city increased rapidly.It makes city construction be more intensive.Especially for subway whose construction period decreased to a large extent.This is a new challenge for the security of subway construction.Recent years,subways with long distances and huge spaces were built rapidly around many big cities in China.It brought lots of accidents such as collapse,roof fall and flood,which is a high risk for construction department and workers.Based on my works in monitoring of subway construction,this paper introduces a new method of monitoring horizontal displacement,and discusses its application in belt-shape projects.
