摘要
在考虑岩土参数空间变异性的情况下,对软粘土地基一维固结平均固结度的概率特征进行了研究,分析了平均固结度的概率特征对渗透系数、孔隙比和压缩系数三参数变异性的敏感性,进行了岩土参数分布类型对平均固结度影响的正交试验,并根据试验结果进行了方差分析,为进一步开展多层地基固结的可靠性分析打下了基础。
With the consideration of the spatial variation of physical parameters of soft clay, the probabilistic characteristics of the one-dimensional average degree of consolidation of soft clay was studied and its sensitivity of variance to permeability, void ratio and compression coefficient of soil was also analyzed. The orthogonal test was applied to research the effect of the distribution type of the physical parameters on the average degree of consolidation. Then, variance analysis of the test results was made. It provides the foundation for further probabilistic analysis of consolidation of layered soil.
