对影响桩振动特性的主要因素进行了分析，结果表明，长径比、桩土模量比及桩底支承系数对桩的动力响应影响显著，而渗透系数作为饱和土的一个重要参数，由于荷载作用时间问题，对桩的动力响应影响较小。 - 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8 9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。
