  2. Saturated sand are testes in the laboratory under the undrained cyclic loading condition with static - dynamic dual purpose triaxial compression test apparatus, which is designed under the cooperation of hohai university and marui co. ltd japan. the results indicate that the stress path approaches from a initial stress point to the failure lines as cyclic loading goes on, and eventually converges on a certain limiting stress path in the vicinity of the failure lines. the stress - strain curve, however, does not converge on a closed hystersis loop ; the shear strain rapidly increases in looser sand or gradually and continually increases in denser sand

    利用河海大學與日本圓井株式會社共同研製的新型的多功能靜動三軸儀進行了飽和砂土循環扭剪不排水試驗，研究表明，對于松砂，剪應變幅度快速地由微小增加到百分之幾甚至百分之十幾，對于緊砂，剪應變幅度逐漸地由微小增加到百分之幾甚至百分之十幾；經試驗初步研究表明用初始有效平均正應力歸一化的有效應力路徑很好的一致性。
