| Abstract: | In order to improve the working condition and stability of rock mass,it has become the a most frequently used measurement to apply various reinforcement anchor in geotechnical engineering.The bolting character of full grouting rock bolt was studied.The load transfer mechanism of tensioned grout anchor and pressured grout anchor was analyzed based on Mindlin's solution of displacement and finite difference method.The distribution of shear stress between bolt-grouting body and rock-body along the anchoring length are deduced based on finite difference method.The influential factors of the distribution of bolt-grouting body shear stress and axial force were analyzed. |
