Analytical Solution on Ground Deformation Caused by Parallel Construction of Rectangular Pipe Jacking

Pipe jacking has been widely used in urban underground engineering construction recent years. Prediction of ground deformation caused by pipe is particularly important for the safety construction. With regard to densely arranged pipes roof structure method, an analytical model stratum disturbance parallel rectangular proposed on basis Mindlin’s displacement solution and stochastic medium theory. The influencing factors such as soil loss, additional thrust excavation face, friction between machine soil, subsequent grouting pressure were comprehensively considered. Then, a 3D numerical simulation case study conducted. results showed consistent agreement with solution, method can take into account asymmetry surface settlement curve induced A discussion law shows that approach reasonably predict provide reference relevant
