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。
Taking the soil skeleton as the hypothesis of elastic porous solution and Terzaghi’s one-dimensional consolidation theory, the general solution of one-dimensional consolidation equation for saturated clay under arbitrary loading is deduced. The Terzaghi consolidation theory solution is a special case of this article. The solution of the consolidation equation and the soil settlement calculation formula for several cyclic loads under sinusoidal, rectangular, triangular and trapezoidal shapes are also derived in detail. At the end of this paper, a preliminary comparison of consolidation test results and theoretical analysis of Xiaoshan clay under rectangular wave loading in Zhejiang Province is made, and the content of further research is proposed.
