| 摘 要： | 采用空间均值的方差的两种算法分析了自相关距离对固结系数的变异性的影响。结果表明,随着自相关距离的增大,固结系数的变异性增大。分析了不同土层的固结系数的不同,变异性对一维平均固结度的影响是不同的。结果表明分析一维固结,应视土层情况和工程性质考虑是否用随机场来模拟土的固结。

| Abstract: | In this paper two methods of calculating the variance of the sample's spatial means are used to study the influence of the self-correlation distance on the variation of the coefficient of consolidation.The analysis results indicate that the variability of the coefficient of consolidation increases with the self-correlation distance increasing.For different variabilities of the coefficient of consolidation of different soils,the influences on the average degree of one-dimensional consolidation are different. |
