| Abstract: | The tunnel of Shanghai center ring located in the intersection of Hongxu-Beihong road is the first case to adopt pipe roof construction method in China, and also the largest tunnel section engineering of pipe roof in soft saturated layer in the world. Based on this case, a creative method of jacking cultivate box witin pipe roof is presented, which is called RBJ construction method (roof-box jacking method). The following aspects are introduced in details to present reference for resemble project in design and construction: these are high-accuracy attitude control of pipe jacking, gridding design method, jacking resisting force control and ground deformation and box attitude control techniques. |
