论红黏土有效孔隙比的确定方法
Determination method of effective void ratio for lateritic soil
摘要
Abstract
The effective porosity is smaller than the actual pore in the lateritic soil.Thus the calculation result is larger by the traditional Darcy formula than the actual value.So it is important to study the calculation method of the effective void ratio of the lateritic soil.The consistency index method,initial gradient method,double layer parameter method,saturated soil quality,combined water content method,m index method,and the compaction degree method derived in this paper were introduced.Their advantages and disadvantages were analyzed.The applicability of the modified formula of Darcy permeability coefficient based on the effective void ratio in the lateritic soil was verified based on the experimental data of 56 groups of variable head permeability.The results show that the effective void ratio should be calculated by different methods according to the permeability of the lateritic soil.关键词
