Soil porosity and pore size distribution [articol]

Abstract

The characterization of pore space is an essential component of the ground investigation process. Natural or artificial processes in the soil are forming or destroying the soil pores and are causing changes in their size and distribution. Since the soil fluid movement occurs in pore, their size distribution is particularly important in defining some soil characteristics. The research presented in this paper include: analysis of porosity and pore size distribution in natural soils, determination of porosity and pore size distribution curve based on suction, building the suction curve by laboratory experiments and mathematical modeling, results processing, highlighting possible effects of soil processes on the porosity and pore size distribution.
