| 摘 要： | 给出了低频梯形循环荷载下单层地基一维固结解。对该循环荷载下地基固结特性、相应的影响因素以及平均固结度、有效应力随荷载的发展和变化规律进行了分析和讨论，并研究了有效应力最大和最小值随荷载的变化规律。在任一周期中，有效应力 的发展并不与荷载的变化同步，而是按一定规律滞后发展。

| Abstract: | An analytical solution to one-dimensional consolidation problem under low-frequency trapezoidal cyclic loading is presented. Based on the solution, the consolidation behavior under the cyclic loading and its influential factors are investigated; and the variation rules of the average consolidation degree and the effective stress with the loading are discussed. Moreover, the principle of variation of the maximum and minimum value of effective stress in soil with the loading is analyzed. It is shown that the development of effective stress is not synchronously with the variation of loading but is in a delayed way. |
