Abstract

Abstract: The moisture characteristic curves of red clay samples with different dry densities: 1.20 g/cm3, 1.31 g/cm3 and 1.42 g/cm3 are measured through soil pressure plates. The results validate that there is a significant impact of dry density on the moisture characteristic curves. With the decreasing of the volumetric moisture content, the matric suction increases with a reducing magnitude before reaching a constant value. The Van Genuchten model can successfully simulate the tested moisture characteristic curves.

Key words: Red Clay, Moisture Characteristic Curves, Soil Pressure Plates, Van Genuchen Model
