几种孔隙比与渗透系数关系的对比
Comparison among Some Relationships between Permeability and Void Ratio
摘要
Abstract
Permeability (Hydraulic conductivity) is a basic parameter, used to describe seepage and consolidation of soil. Presently, large numbers of research show that there are consistent connections between permeability and effective volumetric stress, especially and void ratio. Thereafter, some emprirical relationships between permeability and void ratio were proposed. In this paper, the relationships are transformed to the log k - e coordinates. It is found that △log k linearly increase with △e, and all the ratio Ck of Alog k to △e are function of initial void ratio eo. Meanwhile, the Ck functions of the transformed experimental expressions are compared.关键词
