Abstract: 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.

Key words: geotechnical engineering, anchorage body, stress distribution, numerical simulation
