【Abstract】 Pipe jacking construction may disturb the soil around the pipes and cause soil movements. The mechanism and reason of ground deformation caused by pipe jacking construction are analysed. Combining with the case in study, the regularity of ground deformation is probed. In this case, the maximum ground upheaval is 128 2mm, and generally the ground upheaves at first and then subsides.更多还原
