Damage to Foundations from Expansive Soils
نویسندگان
چکیده
Expansive soils owe their characteristics to the presence of swelling clay minerals. As they get wet, the clay minerals absorb water molecules and expand; conversely, as they dry they shrink, leaving large voids in the soil. Swelling clays can control the behavior of virtually any type of soil if the percentage of clay is more than about 5 percent by weight. Soils with smectite clay minerals, such as montmorillonite, exhibit the most profound swelling properties.

Expansive Soils—problems and Remedies
Expansive soils are one of the examples of tropical soils. These soils pose problems to civil engineers in general and to geotechnical engineers in particular. They cause damage to structures founded in them because of their potential to react to changes in moisture regime. They undergo severe volume changes corresponding to changes in moisture content. Because of their potential to undergo vol...
متن کاملGeotechnical Aspects of Light Structures on Expansive Soils
The geotechnical behaviour of expansive clay soils is investigated by looking into the geomorphologic, geological and climatic conditions and mineralogical composition of the soils in the study area. The geotechnical results are linked with the performance of the foundation as well as structures. Since swell potential and swell pressure are key properties of expansive soils, the swell parameter...
متن کاملModelling of Swelling Parameters and Associated Characteristics Based on Index Properties of Expansive Soils
Presence of swelling soils under the foundations of civil engineering structures particularly lightly loaded structures has caused serious damages around the globe due to their differential up heaving. In this paper, based on the results of swell tests on bentonite mixed clay, correlations for predicting the swelling parameters (i.e., swell potential and swell pressure) have been proposed. Mixi...
متن کاملBehavior of Flexible Pavements on Expansive Soils
This investigation discusses the findings on analysis results of a pavement structure constructed on a relatively expansive material consisting mainly of brown clayey silt in Tebessa, Algeria. Cores were brought to the laboratory from a piece of roadwork. Remolded samples were taken from subgrade of a deteriorated road. The soils were generally found to be of medium plasticity and of a medium t...
متن کاملASSESSEMENT OF SOIL COLLAPSE PREDICTION METHODS
Expansive and collapsible soils are some of the most widely distributed and costly of geologic hazards. These soils are subject to changes in volume and settlement in response to wetting and drying, often resulting in severe damage to structures. Collapsing soils are generally characterized by sudden and large volume decrease at constant stress when inundated with water. A geotechnical engineer...
