摘要
采用双圆盾构施工地铁隧道是解决地下工程空间利用的有效途径。介绍了上海市轨道交通10号线3标同济大学站—大连路站—邮电新村站区间隧道采用双圆盾构施工的方案。重点叙述了引起地面沉降的原因及控制地面沉降的措施。通过工程实际,测得双圆盾构施工中累计的最大沉降量为49mm。
It is an effective way of adopting double-o-tube shield construction to resolve underground construction space usage. Taking a running tunnel (Tongji University Station-Dalian Rd. Station-Youdian Xincun Station), the Bid 3 of Shanghai Metro Line 10 for the example, it adopted the plan of DOT shield construction. The causes and the controlling measures to ground settlement were emphasized in this paper. Its accumulated max settling amount was 49 mm through the construction practice.
