A STUDY OF MODEL OF ROCKBOLT UNIT FOR FINITE ELEMENT METHOD OF LARGE DEFORMATION FOR SIMULATING ROCKBOLT SUPPORTS

Based on the basic theory of finite element method of large deformation,this paper presents a new rockbolt element model for finite ellement method of large deformation.Moreover,the related formulas are deduced,which have successfully solved the problems of simulation and computation of finite element method of large deformation for rockbolt supports.Therefore,they have extensive theoretical significance and practical value in rock and soil engineering.
