The effect of three input factors on stability design was considered: nail length to wall height ratio (A), nail inclination (B) and vertical spacing (C). By altering the parameter variables, the design served to build and acquire a statistically significant mathematical model for optimizing soil nailing wall parameters. The aim is to minimize a single objective function of safety factor and identify the optimal parameters of design among all possibilities.
