| Abstract: | Injecting slurry is usually used to reduce the jacking friction in long-distance pipe jacking. The material of slurry and its property are studied. The reciprocal-action mechanism of soil and mud slurry around pipe in the course of injecting slurry is investigated. The seepage behavior of mud slurry on soil around pipe and the influence of injection on soil movements are discussed, and several problems which should be paid attention to in injecting slurry are put forward. |
