【Abstract】 By using the orthogonal finite element strength reduction experimental method,the influences of soil nailing parameters on support factor have been discussed.The primary soil nailing parameters are analyzed and the optimal values of soil nailing parameters are given. These not only ensure the stability of the slop supported by soil nailing,but also make the designed parameters economic.更多还原
