摘要
在进行上海东方路下立交工程大面积深基坑开挖期间,须严格控制由于上方基坑开挖卸载引起的地铁隧道的位移量,才能保证下方地铁二号线的正常运营。从施工工艺的角度分析了开挖卸载对下卧隧道的影响,提出了减小隧道位移的施工措施。
It is necessary to control tunnel displacement for safeguarding the safety of No.2 line of Shanghai metro during excavating of a large deep foundation pit for intersection under Dongfang Road in Shanghai.The effect on the tunnel due to excavating the upper pit are analyzed and some measures are given to reduce the displacement.
