Abstract

Recently, small-diameter shallow tunnels have often been built using pipe-jacking. This is the sewage tunnel drivage method. This system involves the pushing or thrusting of a drivage machine through concrete pipes ahead of jacks. This method utilizes mud slurry which is formed around the pipes in order to stabilize the surrounding soil. However, the behavior of the soil and the mud slurry around the pipes is not clearly understood. From this point of view, this paper discusses the performance of mud slurry around drivage pipes by means of two-dimensional Eulerian-Lagragian seepage analysis and field data.
