State-of-the-Art-Review of Collapsible Soils [PDF]
Sultan Qaboos University Journal for Science, 2000 Collapsible soils are encountered in arid and semi-arid regions. Such soils cause potential construction problems due to their collapse upon wetting. The collapse phenomenon is primarily related to the open structure of the soil.

Collapse of stone column foundations due to inundation. [PDF]
, 1990 An important problem encountered by foundation engineers involves partially saturated soils which possess considerable in-situ dry strength that is largely lost when the soils become wetted. Foundation design in such soils is difficult at best.

Behavior of Collapsible Soils Improved by Fly Ash and Cement Kiln Dust [PDF]
Journal of Engineering Research - Egypt, 2020 Collapsible soils are metastable soils characterized by voids inside their building, at grain sizes ranging from silt to fine sand. On wetting, they collapse producing distortions that might cause failure of structures.

Soil–water characteristic curve of unsaturated collapsible soils
Journal of the Mechanical Behavior of Materials, 2023 Collapsible soils are almost found in unsaturated states and involved significant engineering problems. Geotechnical challenges of such soils are represented by the hydro-mechanical behaviour during wetting–drying cycles due to the humidity and climate ...

Influence of the structure on the collapse potential and shear strength of a residual soil in the semiarid region of Northeast Brazil [PDF]
MATEC Web of Conferences, 2021 In the last decades, several engineering works have been developed in the Northeast of Brazil, a region marked by the occurrence of collapsible and expansive soils.

A review of the identification methods and types of collapsible soils
Journal of Engineering and Applied Science, 2022 Collapsible soils have caused infrastructural damages resulting in several economic losses and loss of lives in certain cases. The prerequisite for collapse occurring is an open metastable structure; capable of developing in any soil type given the right

Collapsible soils in the UK [PDF]
, 2020 Metastable soils may collapse because of the nature of their fabric. Generally speaking, these soils have porous textures, high void ratios and low densities.

Effect of Initial Water Content on the Collapsibility of Natural and Cement-Treated Gypseous Soils
Civil and Environmental Engineering, 2023 Soils that exhibit high volume change when its water content is changed are considered collapsible soils. Gypseous soils are one of the main types of collapsible soils which can be found in arid and semiarid areas.
