The shear stress distribution of the wholly grouted bolt is analyzed by using a nonlinear finite element method; also the strengthened rock-soil body's properties are researched

which influence the anchorage body's shear stress distribution. Afterwards

a contrastive analysis is done among numerical simulation result

theoretical calculation and experimental result; it indicates that the shear stress distribution in the anchorage body is uneven. Under the small load

the bolt's shear stress distribution range is small but the maximum shear stress is large; with the increase of load

its distribution range tends to expand downwards with a slow speed. The shear stress and its distribution have a close relationship to rock-soil body's properties: the stiffer the rock

the more concentrated the shear stress and the larger the maximum shear stress; on the contrary

the evener the distribution and the smaller the maximum shear stress.
