New slurry pressure type soil-nailing technology and its working mechanism

In soft soil foundation, the strength of soft soils is low and the quality of the construction of the conventional soil-nailing is hard to be controlled. To solve these problems, new slurry pressure type soil nailing technology is developed, and the soil-nailing ultimate resistance is calculated by carrying out the field pullout tests. In addition, the finite element software is adopted to establish the three finite element analysis model for slurry pocket pressure type soil nailing. The transfer law of load is studied, and the effects of the soil conditions and the dimensions of the grouting are analyzed.
