上界・下界つり合い法による土圧問題の解析 An analysis of the earth pressure problems by Upper and Lower Equilibrium Method 西原, 晃 44422 上界・下界つり合い解析 極限つり合い解析 極限解析 土圧問題 upper and lower equilibrium method limit equilibrium method limit analysis earth pressure problem P(論文) The problem of the active and passive earth pressure acting on a rigid retaining wall has been studied ever since Coulomb formulated the limit equilibrium solutions in 1776 . It has long been recognized that such solutions greatly overestimate the passive pressure. With the development of the plasticity theory, many problems have been solved on much more logical basis. The author has examined the logical basis of the limit equilibrium method and the limit analysis, and proposed a set of new methods (Upper and Lower Equilibrium Methods) of obtaining both of the upper and the lower bound solutions. In this paper, the validity of Upper and Lower Equilibrium Methods (ULEM) is examined through analysis of the problem of the active and passive earth pressure by ULEM. departmental bulletin paper 2006-12 application/pdf 福山大学工学部紀要 30 49 56 AN00217655 https://fukuyama-u.repo.nii.ac.jp/record/8260/files/KJ00005781675.pdf https://fukuyama-u.repo.nii.ac.jp/records/8260 jpn
