土钉倾角对斜面加固效果影响的试验研究

itling box tests that model slope failure were carried out on dry and wet sands to investigate the influence of the installing angle of soil nails on slope stability. It was found that the reinforcement is more effective to install soil nails along the direction of the minor principal stress σ3 than perpendicular to the slope surface, and under a certain installing angle, the failure angle of the slope increases with the shortening distance between nails.
