原始语种摘要: Abstract(#br)This study presents stability charts for estimating the stability of rock mass slopes that are suitable for the generalized Hoek-Brown (GHB) failure criterion based on the strength reduction technique. First, in order for implementing the GHB strength reduction, the estimation for the local Mohr-Coulomb (MC) friction angle and cohesive strength from the GHB criterion was incorporated into the strength reduction process in ABAQUS 6.10. Second, stability charts for calculating the FOS of rock slopes with a specific slope angle of β =45° and D =0 are proposed based on this method. Third, the disturbance weighting factors f D and slope angle weighting factor f β are used to quantify the effect of the rock...
