In slopes where a mixture of coarse and fine particles is present, the infiltration of rainfall can cause the migration of fine particles. This migration alters the hydraulic properties of the soil and has implications for slope stability. In this st

Considering the pressure-bearing mechanism of the safety helmet and as an anchored net is subjected to the surrounding rock mass, researchers should regard the support force as a safety criterion. Thus, a method for calculating the anchored mesh supp
