From the results of this consideration, the following notable points are drawn: 1. The local factors of safety for shear strength and the total factor of safety of a slope should be distinguished, however these factors are not distinguished in Bishop's and other methods of slices. 2. The factors of safety for moment may be regarded as the most fundamental for the reason that its physical significance for the stability of slopes is clear. 3. Because ΣS/ΣT (S and T are the resistant shear forces and the equilibrium shear forces along the sliding surface, respectively) is equal to the factor of safety for moment only on the assumption of a circular sliding surface, this expression should be regarded as a formula for calculating the factor of safety only in the case of a circular sliding surface, but not a generalized expression for the definition of the factor of safety.新潟大学積雪地域災害研究センター1986-01jpndepartmental bulletin paperhttp://hdl.handle.net/10191/39064https://niigata-u.repo.nii.ac.jp/records/28164AN0018332703877892新潟大学積雪地域災害研究センター研究年報新潟大学積雪地域災害研究センター研究年報7173178https://niigata-u.repo.nii.ac.jp/record/28164/files/7_173-178.pdfapplication/pdf366.3 kB2019-08-20
