“…Indeed, air is present in the sample in the form of occluded air bubbles in water, forming a homogeneous and compressible pore fluid. The behavior of this fluid is considered in the modeling through a saturation equal to 1 and a compressibility factor taken equal to 6.10 -5 kPa -1 (based on feedback for this soil type [15,16,17]). Figures 3 and 4 show the drying-wetting paths.…”

Abstract. This paper presents an experimental and numerical investigation funded by the French National Project "Terredurable", which is devoted to the study of soils in quasi-saturated state. The experimental study is focused on the behavior of compacted soils on drying-wetting paths and the macroscopic effect of the drying path on shrinkage and cracking. Furthermore, a protocol for image analysis of crack in drying tests was developed. Two approaches are used for the measurement of surface strains and identification of the ultimate stress before the formation of the first crack, using VIC-2D software, and for the monitoring of crack evolution, using ImageJ software. The aim of the numerical approach is to reproduce the drying experiments with a finite difference code (FLAC 3D), in order to understand the stress conditions that can explain crack initiation, without modeling the crack formation itself.
