Experimental study on the pullout resistance of pressure-grouted soil nails in the field
The pullout behaviour of cement-grouted soil nails, particularly in field conditions, is not yet
fully understood. In this study, a series of tests was conducted to evaluate the pullout
response of grouted soil nails in a field slope. A new innovative grouting packer system was
developed to control the grouted length and maintain the cement grout pressure of the
grouted part. By using the grouting packer system, a total of 10 soil nails placed at different
soil depths were grouted with different pressures in the field. The pullout results of present …
