Abstract: Prediction of ground deformation caused by pipe jacking is very important for safe construction. During the construction of pipe jacking, the ground deformation will be influenced by: ①the attitude of pipe jacking machine and the supporting pressure on excavation face; ②the jacking process and the course of changing pipes; ③the grouting process, etc.. To analyze the ground movement during the construction of pipe jacking, a numerical approach is proposed. The Mindlin solution to vertical and horizontal force is used to calculate the ground deformation induced by the face support pressure and the lateral friction resistance, respectively. The Sagaseta method is adopted to consider the ground loss induced by over excavation. A complex variable method proposed by Verruijt is used to simulate the ground movement caused by grouting. Then a 3-D analytical solutions for ground movements induced by pipe jacking is obtained and applied to a case study. The results indicate that considering the grouting pressure can simulate the ground deformation induced by pipe jacking reasonably.

Key words: pipe jacking, grouting pressure, ground deformation
