上海地铁2号线(杨高路～东方路)圆隧道施工技术

Shield Tunnelling Technology Used in the Starting Section of Shanghai Metro Line No. 2

上海地铁2号线杨高路～东方路区间隧道为整个地铁2号线工程中先行施工的区间隧道。在实际施工中,采取均衡施工的目标管理制度,日平均推进速度达到8m,另外,盾构成功地穿越了施工难度极大的上游引水箱涵及管线密布的杨高路、东辉职校和临时动迁房等。

This paper introduces the balanced management in the shield tunnelling of this section with an objective of uniformly driving speed-8m perday. It also presents the technology of shield tunnelling across water supply box and the densely distributed pipe lines and buildings in Yang Gao road and adjacent district.
