摘要
在过滤排水系统中 ,孔径及其分布是非织造土工布的重要指标 ,它与非织造土工布的渗透性能直接相关。利用PoissonPolyhedron理论 ,在前人研究的基础上分析了非织造土工布的理论孔径分布及其最大孔径 ,并根据Hagen Poisseuille定律探讨了非织造土工布的孔径分布与其渗透性能间的关系 。
In the field of filtration and drainage,pores size and their distribution of nonwoven geotextile are the most important parameters,which are directly related to its permeability.Based on the former researchers' works,the theoretical pore size distribution and maximum pore size of nonwoven geotextile are studided by means of Poisson polyhedron theory.The relation berween pore size distribution and permeability of nonwoven geotextile is derived by using Hagen Poisseuille Law.The theoretical calculation value of vertical permeability coefficient is approximately agreeable to the expetimental result for a nonwoven geotextile sample.
