The paper presents a detailed numerical analysis to elucidate the failure pattern of the pit wall, the mechanism of the soil - nailed supporting system and its spatial behavior. firstly, a typical two - layer sand - cobble deposit was chosen for a detailed 2d - fem study. it was shown that due to the distinct behaviors of the upper soft sand layer against the much stiffer lower cobble layer, a bi - linear plane failure was recommended to be used in the limit equilibrium analysis
