Considering the similitude law for shaking table test, we study the test results and obtain some conclusions which are a ) generally, the silty soil in test box liquefies and the liquefied time has relation with the amplitude of acceleration, b ) when the intensity is on and above eight degree, the silty soil deposit will be liquefied dramatically, c ) the relationship of the pore water pressure is relevant to the cycle loading which represents when the cycle loading ranges from little to great, the relationship is represent as a concave curve, or else as a protruding curve and tends to stability. ( 3 ) based on the triaxial compression test and the resonant column test, some studies are made such as a ) the duncan - chang parameters of constitutive model, b ) the dynamic shear modulus ratio and c ) the damping ratio of the site soil deposits. in order to deal with the test data, a computer program is compiled
（ 2 ）利用小型振動臺進行了k _ 0固結狀態下粉土的振動液化模擬研究，通過分析正弦荷載作用下的試驗資料，驗證了粉土的孔隙水壓力增長模式的合理性；從微分方程推導了基於土體振動臺模型試驗的相似律，並從模型實體、孔壓時程曲線和相似律等方面做出了分析，得出了如下結論：在小型振動臺試驗中，模型箱中的粉土都發生了液化，液化的時刻和輸入加速度幅值有關，而對頻率的變化不太敏感；粉土在相當於8 9度地震烈度的加速度幅值作用下可能產生嚴重的液化；孔壓的增長曲線形狀與施加的荷載有關：當施加荷載為由小到大的形式時，曲線形狀為上凹的曲線；當施加荷載為等幅的正弦荷載或荷載幅值由大到小時，曲線形狀為上凸的曲線，且逐漸趨于穩定。 -
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。 -

Merely the fatigue strength in uniaxial tension or compression under constant - amplitude cyclic loading is given in the existing design code. the design result by using the fatigue strength in the code is apt to conservative under variable - amplitude or triaxial cyclic compression loadings, but sometimes apt to dangerous in uniaxial or triaxial tension - compression fatigue loadings
現行規范中，僅有混凝土單軸、等幅波動拉伸和抗壓強度指標，採用這些指標進行設計，會導致設計結果有時偏於保守，如變幅及多軸壓疲勞；而有時又偏於危險，如單軸及多軸波動拉-壓疲勞。 -
