Title: Amendment of Analytical Solution on Stability of Joint Rock Slope Based on Finite Element Method
Abstract: The changes of stress field and formation mechanism of joint development of rock slope under the condition of man-made or natural environment were studied by finite element method;the sensitivity of factor of slope stability with tension joints was comparatively analyzed by strength reduction finite element method;the analytical solution on stability of non-through joint rock slope was amended.The results showed that the unloading and weathering resulted in stress redistribution and concentration of slope and tension joints development down vertical or tilts to the free face slightly,and the slope would damage when tension joint connected with gently inclined joint;next to the inclination and through degree of shear joint,the most sensitive factors of slope stability were strength parameters of joint;the through degree of joint investigated difficultly could be equivalent replaced by strength parameters of joint,and the analytical solution on stability of non-through joint rock slope was amended according to Mohr-Coulomb strength criterion.
