Evaluation of the collapsibility of a sandy soil by in situ collapse tests

2005
This paper presents some results of a research project aiming at understanding the behavior of collapsible soils in order to improve settlement prediction in foundation design. Two series of in situ tests were performed: one using circular load plate (0.80m of diameter – Group 1 test) and another using an equipment called &ldquo ...

Determination of Collapse Potential of Soils

Geotechnical Testing Journal, 1988
Abstract A review of various criteria that have been proposed to identify collapsible soils and test techniques, which are used to quantify the amount of collapse, is presented. The results of a series of laboratory single and double oedometer collapse tests conducted on three metastable loess soils are presented to illustrate problems ...

Collapse behaviour of a lateritic soil

Geomechanics and Geoengineering, 2015
Collapsible soils are problematic by nature. They undergo collapse or sudden settlement or subsidence under a given stress when their water content is increased. Collapse is characterised by collapse potential expressed as ΔH/H x 100, where ΔH is collapse compression. The amount of stress applied and the water content at the time of collapse govern the

Stabilisation of collapsible soils

2015
Collapsible soils are prone to considerable volume change as a result of wetting. The presence of collapsible soils under the footing of industrial or residential buildings can bring about irrecoverable and considerable damage to the supporting structures due to settlement of the underlaying soil upon wetting.

Types and Distribution of Collapsible Soils

1995
Collapsible soils are metastable and must have an open structure, that is the soil particles must be in an open packing which is capable of becoming a (significantly) closer packing. A granular material with angular particles compacted on the dry side of optimum can form a structure which is capable of significant further densification, but the classic

Mechanisms of Collapse of Soil Structure

1995
Three aspects are clarified in the Introduction: the level of analysis (micro- or macromechanical), the definition of collapse (specific type of yielding marked by singularities) and the role of state parameters. Field examples of collapse are presented to emphasize the practical importance of collapse studies.
