Slurry pipe-jacking was firmly established as a special method for the non-disruptive construction of the underground pipelines of sewage systems. Pipe-jacking, in its traditional form, has occasionally been used for short railways, roads, rivers, and other projects. Basically the system involves the pushing or thrusting concrete pipes into the ground by a number of jacks. This method utilizes mud slurry that is formed around the pipes in order to stabilize the surrounding soil. In slurry pipe-jacking, the performance of the mud slurry plays an important role in the pushing process. Thrust in slurry pipe-jacking can be predicted by evaluating the resistance between the mud slurry and the concrete pipes and the resistance between the soil and the pipes in linear and curved jacking area. This paper discussed about this point.
