Abstract

A 3D simulation model considering the shear deformation between the high pre-stressed yield bolts and the rock was suggested,and the corresponding program of the finite element method was developed.Due to simulating bolts with the 2-noded member elements and the 4-noded bolt elements,the proposed method could be used for the simulation of anchorage cables,general bolts and piles.And it could simulate the mechanical properties of the high prestressed yield bolts well.
