Abstract: 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.
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.
宽尾墩—跌坎底流消力池联合消能工试验研究  [PDF]
南水北调与水利科技 , 2013,
Abstract: 通过水工模型试验着重分析比较了宽尾墩—跌坎联合消能工与跌坎以及常规消能工消力池内的水流流态、临底流速以及脉动压力等。试验结果表明,该种新型的消能方式改善了跌坎消力池内的水流流态,降低了消力池内的临底流速和脉动压力,缩短了消力池的长度,减轻了下游河道的冲刷,并且能很好的地利用宽尾墩良好的消能率,克服了宽尾墩挑射水流对消力池底板的冲击问题,为类似工程提供了参考,同时也丰富了泄洪消能工的型式。

Abstract: The deformation and stresses of soil by pipe-jacking are calculated with 2D and 3D finite element methods. The calculations considere three factors independently,that is,the soil press on the head of pipe-jacking,friction in soil and deviation of pipe-jacking head. Their influence on earth surface deformation are examined and some useful conclusoions are drawn.

In Japan when urban infrastructures need to be constructed, the difficulty of utilizing the ground or shallow strata will lead to a more frequent use of the deep strata. The common construction methods are open-cut, pipe jacking, and shield methods. In recent years, a new pipe jacking method has been established that can be adapted to 20 m below the ground or more. Using this method, the drivage machine and the jacking pipe continue to move an underground until the completion of the driving. Therefore an over-cutting area (so-called tail-void) must be formed to lower the friction between the ground and the pipe. The tail-void is filled with lubrications. However, because the stress release from the ground continues to advance when the tail-void is formed, hence there are some challenges required to cope with the stability of the surrounding ground. In order to utilize the pipe jacking method in the deeper strata layers, the theory, analysis and installation of tail-void have to be systemized, and such systematic data must be stored. Therefore, the conditions of tail-void in the deep pipe jacking method are discussed using numerical analyses.
