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)利用小型振动台进行了k_0固结状态下粉土的振动液化模拟研究,通过分析正弦荷载作用下的试验资料,验证了粉土的孔隙水压力增长模式的合理性;从微分方程推导了基于土体振动台模型试验的相似律,并从模型实体、孔压时程曲线和相似律等方面做出了分析,得出了如下结论:在小型振动台试验中,模型箱中的粉土都发生了液化,液化的时刻和输入加速度幅值有关,而对频率的变化不太敏感;粉土在相当于89度地震烈度的加速度幅值作用下可能产生严重的液化;孔压的增长曲线形状与施加的荷载有关:当施加荷载为由小到大的形式时,曲线形状为上凹的曲线;当施加荷载为等幅的正弦荷载或荷载幅值由大到小时,曲线形状为上凸的曲线,且逐渐趋于稳定。
