Description
For the purpose to evaluate the effects of dimension and rigidity of plastic bearing plate for soil nailing on the shearing resistance, a series of direct shear tests were conducted on reinforced slope models that were made in a shear box. Using plastic bearing plates with different sizes and stiffness as model slope protection works, the experiment results showed that the bearing pressure induced by plates applied as vertical pressure to the soil block that lead to increase in shear resistance, and that the shear resistance increased with the increase in covering ratio and rigidity of bearing plate. Also, a linkage frame connecting nail heads was found effective due to the increase in covering ratio and the overall stiffness of the slope works.
