Performance of [PDF]

open access: yesAlexandria Engineering Journal, 2015
Soil collapse occurs when increased moisture causes chemical or physical bonds between the soil particles to weaken, which allows the structure of the soil to collapse.

Collapse of stone column foundations due to inundation. [PDF]

open access: yes, 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.

Influence of acid environment on Collapsibility of Loess [PDF]

open access: yesE3S Web of Conferences, 2021
Cemented connection of loess is an important internal factor of loess collapsibility, which has a direct impact on its collapsibility. In this study, different concentrations of nitric acid were added to the immersion solution of loess collapsibility ...

Behavior of Collapsible Soils Improved by Fly Ash and Cement Kiln Dust [PDF]

open access: yesJournal 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.

The cascade structure of linear instability in collapsible channel flows [PDF]

open access: yes, 2008
This paper studies the unsteady behaviour and linear stability of the flow in a collapsible channel using a fluid–beam model. The solid mechanics is analysed in a plane strain configuration, in which the principal stretch is defined with a zero initial ...

State-of-the-Art-Review of Collapsible Soils

open access: yesSultan 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.

A simple laboratory method to simulate calcite-bonded loose-structured soil samples for collapsibility study

open access: yesJournal 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

Modelling the behavior of inundated collapsible soils

open access: yesEngineering Reports, 2020
The properties of collapsible soil exhibit a lot of sensitivity toward the increase of water content, especially when the soil is close to the dry state.

Treatment of Swelling and Collapsible Characteristics of Soils By Waste Building Materials [PDF]

open access: yesKirkuk Journal of Science, 2018
Volume changes occur when soil exposed to water, for expansive soil the size of soil increases and produce pressure on surrounding area, but for collapsible soil it cause large amount of settlement under a certain load, the amount of swelling and ...

Treatment of collapsible soils by mixing with iron powder

open access: yesAlexandria 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.
