【Abstract】 On the basis of the representative undisturbed samples of slity clay in Wuhan, China and imitated several stress paths that may occur in the excavation erection, a series of laboratory triaxial shear tests are accomplished to research the effect of stress path upon the consolidated-undrained strength index-friction angleφ_cu, The conclusion of the experimental research can be applied to the stability calculation of excavation.更多还原
