| 摘 要： | 研究了在循环荷载作用下具有双面半透水边界的饱和粘土层的一维固结问题。根据瞬时加载条件下的解答，采用积分方法得到了循环荷载条件下的解析解。根据解析解的结果，通过计算分析了边界条件和加载条件对土体固结过程的影响，可知：砂垫层和下卧层的渗透性减小会明显减缓固结过程；在循环荷载的一个周期内，孔压和固结度都会达到最大值和最小值各一次。

| Abstract: | One-dimensional consolidation of soft clays under cyclic loadings taking into account the impeded boundaries is studied in this paper. According to the solution in the condition of constant loading, the analytical solution under cyclic loading is obtained using the integral. method Based on the analytical solutions, the influence of loading and boundary conditions on the consolidation behavior of soils is investigated and It can be seen that a decrement in permeability of sand mat and subjacent bed will reduce the rate of consolidation significantly and that the consolidation rate and the pore water pressure reach the maximum and the minimum once in each cycle for cyclic loading. |

| Keywords: | one dimensional consolidation impeded boundaries saturated soil cyclic loadings |
