摘　　要：以室内动三轴试验为基础,对黄河三角洲沉积土(粉质土)进行振动液化试验研究,发现在循环荷载作用下,其振动孔压比与振次比之间满足双曲线关系,粉质土振动初期孔隙水压力急剧上升,随之逐渐趋于稳定,并分析了产生这种现象的原因。Based on the results of the laboratory dynamic triaxial tests,an experimental study was carried out on the dynamic liquefaction of the deposited soil in the Yellow River Delta.It was concluded that under the cycle loading,the development of dynamic pore water pressure in silt differs from the sand,and its curve can be fitted by hyperbola.
