摘    要:将土骨架当作弹性多孔解质和采用Terzaghi一维固结理论中的假设,本文推导了饱和粘土在任意荷载作用下的一维固结方程的通解。Terzaghi固结理论解是本文的一个特例。还对正弦,矩形、三角形和梯形等波形的几种周期荷载下固结方程的解和土层沉降计算式进行了详细推导。文末就浙江萧山粘土在矩形波形荷载作用下的固结试验结果和理论分析作了初步对比,并提出进一步研究的内容。

关 键 词:饱和粘土  一维固结  周期荷载

Abstract:In this paper,the authors derived a general solution of 1-D consolidation for saturated clay under various cyclic loadings in terms of integration,and o-btained the solutions of clay layers subjected to step loading,and square,triangular,sinusoidal and trapezoidal cyclic loadings with the same assumptions as Terzaghi's 1-D static consolidation theory,which is only a special case of the general solution herein.In the meantime,the authors conducted a series of consolidation tests on Xiaoshan Clay under cyclic square loading in the laboratory with various pressure amplitudes and periods.The comparisons between theory and experimental results were made and some conclusions were drawn.
Keywords:Saturated clays 1-DConsolidation Cycli loadings
