%X 摘要 采用STS(steel tube slab)新管幕工法建造沈阳地铁九号线奥体中心站.通过钢管顶进现场试验，对顶管过程中的地表竖向变形及顶管顶力进行监测.经过对监测数据的整理分析，重点研究了顶管过程中地表竖向变形及顶力的变化规律，总结出顶管顶进过程中地表横断面变形规律及地表变形随顶进距离的变化规律，并对其变形机理展开分析.根据顶管顶力监测值得出STS新管幕特殊顶管形式下适合沈阳地区的顶力估算方法，对STS新管幕工法的应用及发展具有重要的参考意义.</br>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.
