Numerical simulation on behaviors of soil nailing

An FLAC program is carried out to simulate the change of nail's length,inclination,assign the way and soil layer parameter to the influence of the horizontal displacement of foundation pit and the greatest axel strength of soil nailing. The result of study shows: In order to control the deformation of foundation pit, we should increase soil nailing length properly, but it can not be too long either; In order to control the deformation of foundation pit, the soil nailing should be nailed to the direction of the level or close to level.
