Abstract The paper presents a new single-surface elasto-plastic model for unsaturated cemented soils, formulated within the critical state soil mechanics framework, which should be considered as an extension to conditions of recently proposed constitutive law saturated structured soils. has been developed with main purpose inspecting mechanical instabilities induced in natural soils by bond deg...

We present a new two-parameter expression for relative hydraulic conductivity (RHC) of partially saturated soils. It is based on the premise of Assouline et al. [1998] that soil structures evolve from a uniform random fragmentation process. This assumption allows us to derive hydraulic properties of soils (water retention curves and unsaturated hydraulic conductivity) from primary properties, s...

Abstract Collapsible soils are almost found in unsaturated states and involved significant engineering problems. Geotechnical challenges of such represented by the hydro-mechanical behaviour during wetting–drying cycles due to humidity climate conditions. The main objective this paper is investigate soil–water characteristic curve (SWCC) collapsible soils. In study, three types were investigate...
