无粘性粗颗粒土渗透性的影响因素分析

Influencing Factors of the Permeability of Cohesionless Coarse-grained Soil

粗颗粒土是指粒径在0.1mm以上的颗粒占一半以上的土,无粘性粗颗粒土的粒径在0.01mm以下的细粒含量不足5%,其中含有砂砾石、碎石等,所以可以自由的进行排水。而无粘性粗颗粒土的渗透性是一个重要的指标,且受到很多因素的影响,在本文中我们对无粘性粗颗粒土的渗透性影响因素进行研究分析,为无粘性粗颗粒土工程进行有利的探索。

Coarse-grained soil refers to the soil over half of which has particle size above 0.1 ram. The content of the smalls with particle diameter under O.Olmm of cohesionless coarse-grained soil is less than 5%, including sandy gravel and macadam, allowing free drain of water. The permeability is an important indicator of cohesionless coarse-grained soil and is affected by many factors. This article analyzes the influencing factors of the permeability of cohesionless coarse-grained soil, doing helpful exploration for cohesionless coarse-grained soil engineering.
