摘要

饱和局部非均匀土在动载作用下力学响应的研究一直是动力学领域的难点，如何描述非均匀介质的局部结构，衡量其对宏观孔压产生和消散的影响，目前尚无成熟的理论模型和分析方法。基于有关局部非均质土波动理论的最新研究成果，建立能够描述局部结构对孔压增长和消散过程影响的动力学模型。针对周期荷载作用下的一维饱和岩土层，获得孔隙水压分布的解析解。分别以松弛时间和荷载频率为变量，定量地分析这两个参数对孔隙水压发展的影响趋势，并确定两者对孔压发展的敏感区间，以上述分析为基础，提出对应孔压极值时松弛时间和荷载频率的关系曲线。分析结论对非均匀饱和土动力学的理论研究和工程应用有一定价值。

Abstract

The mechanical response of the saturated local inhomogeneous media under the cyclic loading has always been the rsearch difficulty in the soil dynamic field. How to describe the local structure of the inhomogeneous soil

weighting the influence of which on the macroscopic pore-pressure; all of them remain undetermined. In this paper

a model that can describe the influence of the local structures on the growth and dissipation of the pore pressure is established; basing on which

the analytical solution of the pore pressure is attained in the one-dimensional saturated soil layer bearing periodic load. Taking the relaxation time and the load frequency as variables

the influence trends of which on the pore pressure are analysed quantitatively; and the sensitive range of them are determined. Basing on the analysis

the relation curves between the relaxation time and load frequency are proposed when the pore pressure reaches maximum. All conclusions will contribute to the academic and engineering application in the research field of inhomogeneous media soil.
