Abstract

Abstract: STS (steel tube slab) method was used to construct the Olympic sports center station of Shenyang subway line 9. By field test of the steel pipe jacking， the vertical deformation of ground surface and pipe-jacking force were measured， and their changing laws during jacking were analyzed based on the monitoring data. The ground surface deformation laws in the cross section during jacking were summarized and the changing laws of ground surface deformation with the increase of jacking distance， along with the deformation mechanisms were analyzed. The pipe jacking force estimation method based on the filed mornitoring data is suitable for the strata in Shenyang， and could be used as an important reference to the application and development of STS method.

Key words: STS (steel tube slab) method, subway station, ground surface deformation, pipe jacking, jacking force calculation
