Abstract


A dynamic numerical simulation model of bedding rock slope with bolts was established using FLAC3D program. The alteration of dynamic response with displacements and accelerations at observation points along the slope surface was set as analysis basis. Further study was carried out which has been aimed to make comparison of dynamic response when the rock bolts were set up. Then the influence of static force and earthquake on axial force applied on the bolts was discussed in detail. It demonstrated great help for the dynamic stability analysis and slope design when it is supported with anchor under earthquake.
