ABSTRACT: Shanghai’s subway construction has entered a new period of rapid development. A notable characteristic of subway network construction is that the construction environment is increasingly complex. Take Shanghai subway line 10 as an example, in the position of Shajinggang Bridge on Siping Road, the shield machine will have to pass through the bridge’s pile foundation. Since the embedded depth of piles has already run through the entire tunnel section, these piles have to be pulled out or cut off. But, as one of the main arteries of Shanghai city, Si Ping Road has big traffic flow, and it does not allow the traffic volume to be affected during the construction period. What’s more, there are intensive residential quarters around the bridge and the construction space is limited. Therefore, this paper will mainly introduce how the pile underpinning technology can be used in the subway construction of Shanghai area for the first time.
