The nonlocal friction law proposed by Oden et al was modified and the modified nonlocal frica- tion model to analyze the wholly grouted anchor was used.Based on Mindlin's solution of displacement,an elastic solution of shear stress on bolt surface for wholly grouted anchor was derived.Wholly grouted an- chor was analyzed by using the modified nonlocal frication model,the nonlocal effect on the contact sur- face stress distribution was shown here and the solution of shear stress on bolt surface was given.The re- sults were compared with those obtained by the modified nonlocal frication model and local frication model and the experimental results in references.It is found that the result obtained by modified nonlocal frica- tion model coincides reasonably well with experimental results,and coincides better than the local frica- tion model.The result shows that the nonlocal friction law is more practicable.
