摘要
Pull-out bearing capacity of soil nail is a key parameter of soil nailing design, the calculation method supplied by the standard is too romantic. Pull-out bearing capacity of soil nailing is primarily controlled by interface strength of soil and nail, soil strength around the soil nail, soil press from upper soil and material strength of soil nail. Based on the different conditions, the styles of soil nail pull-out failure can be classified as column shear failure on the interface between soil nailing and soil, soil shear failure around soil nail, composite shear failure and material yield failure of soil nail.
