The experimental study on frictional sliding characteristics of 13 kinds of gouge in 5 points of Haiyuan fault was made by double shear test method.The experiments show that the existence of Haiyuan fault gouge is helpful to remove the stick-slip and to increase the frictional strength.Here are the average of friction coefficient of gouge in 5 points:Jingtai 0.760,Hasishan-0.728,Dagoumen-0.669 Ciergou-0.644,Caixiangbao-0.684.
