| 摘 要： | 上海轨道交通10号线溧阳路站-曲阳路站区间隧道的施工中,盾构在推进至四平路沙泾港桥位置时,须从桥的桩基中穿过。由于桩的入土深度已经贯穿了整个隧道断面,导致必须对桩基进行拔除或切断等处理。为在去除影响盾构推进障碍物的同时保证施工中旧桥功能的发挥,提出适合本工程的托换及除桩技术方案,并提出相应的辅助施工技术,为顺利施工提供借鉴和指导作用,并达到减小社会影响、缩短施工周期和降低工程造价的目的。 |

| Abstract: | During the construction of the interval tunnel from Liyang Road station to Quyang Road station of Shanghai Metro Line 10, the shield machine will have to pass through the bridge＇s pile foundation when it arrives at the position of Shajinggang Bridge on Siping Road. Since the piles run through the entire tunnel section, they must be pulled out or cut off. Therefore, in order to ensure the old bridge＇s normal traffic role while removing the barriers which affects the advance of shield machine, pile underpinning and pile removing technologies as well as relative auxiliary construction technologies are proposed in this paper. It not only provides reference and guidance for the construction of this project but also helps to achieve the purpose of decreasing social impact, shortening construction cycle and reducing construction cost. |
