上海市轨道交通双圆区间隧道衬砌圆环设计探讨

Lining Ring Design of DOT Running Tunnel Section of Shanghai Rail Transit Yangpu Line

随着城市空间的不断开发,地下空间资源日益紧张、环境制约要求增多,对已有的设计施工技术提出了许多新的课题,结合上海隧道轨道交通 M8线工程方案研究,介绍其中双圆区间隧道衬砌圆环的设计和计算。

With the development of urban space,underground space is increasingly stringent.And ambient environment gives more confinements to construction.This requires new study on existing design and construction technolo- gies.This paper summarizes the design and calculation of DOT segment on the basis of scheme design of Shang- hai Rail Transit Yangpu Line.
