【摘要】 利用循环三轴试验对城市垃圾土的动力特性进行了研究。试验中对试样分别施加两种不同荷载，一种为循环压缩，另一种为循环压缩和伸长荷载，分别模拟交通荷载和地震荷载情况，循环荷载频率为1Hz。对城市垃圾土的动模量和振动残余应变试验结果进行了分析，并给出了计算公式。更多还原

【Abstract】 A inveedgation was carried out into stiffness and residual strain of municipal solid waste based on the data bo cyclic triallal tal in thes paper . Two different types of cyclic loads using a sinusoidal cyclic axial stress with for of 1 Hz were applied to the specimen , one on the triaxial compression side and the other on both cimpression and drion side. The results of modulus, residual strain are driewed and the formulation is presented.更多还原
