浅议南通地铁一号线一期工程07标段的工程问题

Preliminary Discussion on Some Technical Issues of No.7 Tender of No.1 Engineering of Nantong No.1 Metro Line

介绍了南通市轨道交通1号线的线路走向、周边环境、07标段的工程内容和所处的地质情况，在此基础上提出了07标段需要研究解决的几个工程问题，即：异形深基坑施工周边地层变形规律及支护技术、超长钢筋笼无槽壁加固地下连续墙施工技术、施工渣土节能环保综合利用技术。

This paper introduces the metro line routing,surround environment,project task of No.7 tender and engineering geological condition of Nantong metro line one. Some engineering technical issues needing to be studied during construction are put forward,i.e, surround ground deformation law and support technology of abnormity deep excavation pit,construction technology of super long steel cage concrete diaphragm wall without groove wall support,and energy conser- vation and environmental protection synthetic utilization technology of construction muck.
