Abstract:
The Jingshunlu Station of Beijing Subway Line 14 is an open-excavated station, whose south end is shield interval. The conventional method which finishing station construction before shield arrival could not be used due to adjustment of station position and delayed early work. Combined ground and in-pit strengthening measures were adopted to solve the soil instability and water leakage problems around tube piece. Optimum design and construction control were carried out to guarantee station foundation pit safety, and relevant construction problems were discussed. This project provided certain references for similar projects in Beijing and other regions of China.
