本文给出了一般时变荷载作用下饱和土层一维固结分析的解析解。一个简单的计算程序，利用傅立叶级数的实际应用提出。通过选择傅立叶级数的适当周期，可以考虑单次载荷和循环载荷。一些与现有的理论解决方案的比较，以评估所提出的程序的准确性。此外，在本研究中进行的oedometer测试，并从一个有据可查的情况下的历史，关于一个大的路堤上建造的可压缩的土壤的实验结果进行了分析，使用此解决方案，以评估的固结系数的situation.Keywords：一维固结，随时间变化的加载，超孔隙水压力，理论解，傅立叶级数。
This paper presents an analytical solution for the analysis of one-dimensional consolidation of saturated soil layers subjected to general time-dependent loading. A simple calculation procedure that makes use of the Fourier series is proposed for practical applications. Both single loads and cyclic loads can be considered by choosing a suitable period for the Fourier series. A number of comparisons with existing theoretical solutions are shown to assess the accuracy of the proposed procedure. Moreover, the experimental results from oedometer tests performed in the present study and from a well-documented case history concerning a large embankment constructed on compressible soils are analysed using this solution to evaluate the coefficient of consolidation of the soil.Key words: one-dimensional consolidation, time-dependent loading, excess pore-water pressure, theoretical solution, Fourier series.
