Identifying Collapsible Soils from Seismic Cone (SCPT): A Qualitative Approach
Buildings, 2023 Collapsible soils are unsaturated low-density soils that undergo abrupt settlement when flooded without any increase in the in-situ stress level. The first stage of the site characterization is identifying collapsible soils, since these are problematic ...

Treatment of collapsible soils by mixing with iron powder
AEJ - Alexandria Engineering Journal, 2018 Collapsible soils are meta-stable soils which present a potential for a large deformation and a complete change to the whole particle structure after wetting, with or without loading.

Experimental investigation of the properties of collapsible soil stabilized by colloidal silica [PDF]
Scientific ReportsCollapsible soils pose significant geotechnical challenges due to their tendency to exhibit high strength under natural moisture conditions but undergo substantial settlement upon wetting. To address this issue, various stabilizing agents, including lime,

Soil water characteristic curve parameters of collapsible sand in Lambayeque, Peru [PDF]
MATEC Web of Conferences, 2021 Several structures are built on collapsible soils in the mining and petroleum industries and on civil sites. In order to analyze the stability of such structures, one must properly study the unsaturated soil behavior.

Soils and Foundations, 2023 Collapsible soils are typically found in arid regions and often have an aeolian or alluvial origin. In their natural states, they may have a low moisture content and cemented structure that can contribute to high strength and stiffness; however, wetting ...

A Unified Two Independent Stress Variable Approach to Moisture-Change-Induced Unsaturated Soil Volume Change [PDF]
E3S Web of Conferences, 2023 In 1968, Matyas and Radhakrishna introduced the concept of the state surface, demonstrating that unsaturated soil volume change is dependent on two independent stress state variables, net total stress and suction.

Journal of Engineering and Applied Science, 2022 Calcite is one of the commonest bond elements in natural collapsible soils. Where calcite occurs in significant amounts, the soils are considered calcareous. Collapsible soils are characterised by high porosity, high-void ratio, and low-dry density, with
