| 摘 要： | 研究了变荷载作用下考虑土的流变特性时的饱和软土层的一维固结问题，通过Laplace变换得到了瞬时加载条件下的解析解，进而根据瞬时加载条件下的解，通过积分的方法，得到了变荷载条件下的解析解。并且根据解析解的结果，通过编程计算作出了几个主要影响因素对固结过程的影响曲线图。结果表明：?1的取值对固结曲线的形状有显著影响；随?0的减小，固结度减小，固结速率减缓。

| Abstract: | The problem of one-dimensional consolidation of soft clays under time-dependent loadings taking account of rheological characteristics of soils is studied. By using Laplace transform, the solution in the condition of constant loading is obtained. Based on this solution, the analytical solution of time-dependent loading is developed using the integral method. By the analytical solution, the influence of some major factors on the consolidation behavior of soils is investigated and the relevant results are presented in graph forms. It is shown that the form of the consolidation curve is affected obviously by ?1 and that the degree of consolidation and the speed of consolidation reduce with the decrease of ?0. |
