Collapsible Behavior of Lateritic Soil Due to Compacting Conditions
(2020-10-01)
Soil collapse is a major geotechnical problem that causes architectural and structural damage to buildings and engineering infrastructure. Losses due to soil collapsibility have an economical aspect and the study of these ...
Revisiting Classical Methods to Identify Collapsible Soils
(Brazilian Soc Soil Mechanics & Geotechnical Engineering, 2015-09-01)
The paper revisits and updates two expedite methods used to identify the occurrence of collapsible soils. The methods were proposed by Gibbs (1961) and de Mello (1973) and have in common the assumption that collapsible ...

Collapse susceptibility mapping using srtm data obtained from topodata project
(2015-01-01)
The occurrence of collapsible soils and collapse processes due to disruptions in water and sewage networks is the main urban environmental problem concerning material losses in many cities of southeastern Brazil. This work ...
Settlement of Footings on Compacted and Natural Collapsible Soils upon Loading and Soaking
(2021-04-01)
Collapsible unsaturated soils experience large volumetric compressive deformations upon wetting. Soil collapse is a geotechnical problem that occurs in different regions of the world and profoundly impacts buildings and ...
Influence of the microstructure in the collapse of a residual clayey tropical soil
(SPRINGER HEIDELBERG, 2009)
A typical residual clayey soil originating from basalt in southern Brazil has been analyzed in order to assess the influence of wetting-induced deformation and microstructural features on the collapse behavior. Single and ...
Using a Seismic Dilatometer to Identify Collapsible Soils
(2021-01-01)
Collapsible soils are unusual geomaterials found in several regions of the world. These soils undergo sudden and large volumetric compressive deformations upon wetting under constant loading. It is a problematic soil that ...
Improvement of collapsible soil behavior of a lateritic soil using rice husk ash
(2016-01-01)
Great areas of Brazil present lateritic soils, such as the northeast and the south. Some of these soils have, as main characteristic, instable structures that can present considerable volumetric deformation in the presence ...
Evaluation procedures for colapsible soils through correlation between edometric tests and spt testsProcedimentos de avaliação de solos colapsíveis por meio de correlação entre ensaios edométricos e ensaios spt
(2021-10-18)
The term collapsibility of soils is not always understood, since engineering projects rarely take into account the effects caused by the phenomenon, which is responsible for several problems in earthmoving services, channels, ...
The Role of Collapsed Bank Soil on Tidal Channel Evolution: A Process-Based Model Involving Bank Collapse and Sediment Dynamics
(American Geophysical Union, 2019-11)
We develop a process-based model to simulate the geomorphodynamic evolution of tidal channels, considering hydrodynamics, flow-induced bank erosion, gravity-induced bank collapse, and sediment dynamics. A stress-deformation ...
