| Abstract: | Parameters of shear strength from triaxial compression test are widely used in project construction. Triaxial compression test has strict requirements in equipment, soil samples and operation etc. and there are many factors influencing the test result. This paper analyzes manifold effect on trixial compression test, such as the restriction of gum membrane, velocity of shear strain, deformation of stress measure ring etc. and puts forward appropriate revising method of efficiently improving test precision. |
