Numerical Modeling of Desiccation Cracking in Compacted Soils
Desiccation cracking and its implications will be more of an issue due to the global warming trends. Soils tend to shrink when they lose moisture. In particular, fine-grained soils are susceptible to shrinkage and the resulting volume change. Shrinkage can cause cracking of soils that can adversely impact the engineering properties and behavior of the soils. As a result, the integrity of struct...
متن کاملJunction formation during desiccation cracking.
In order to provide a sound physical basis for the understanding of the formation of desiccation crack networks, an experimental study is presented addressing junction formation. Focusing on junctions, basic features of the network determining the final pattern, provides an elemental approach and imparts conceptual clarity to the rather complicated problem of the evolution of crack patterns. Us...
متن کاملSome Investigations on Cracking Characteristics of Soils
Fine-grained soils, in particular, expansive soils are prone to cracking. For these soils swelling-shrinking potential is quite high and hence they exhibit adverse affect on overall stability of geotechnical structures. This phenomenon may also be responsible for alteration of various engineering properties of soils such as hydraulic conductivity, water and leachate penetration, solute transpor...
متن کاملDesiccation of a clay film: cracking versus peeling.
We report a simulation study on competition between cracking and peeling, in a layer of clay on desiccation and how this is affected by the rate of drying, as well as the roughness of the substrate. The system is based on a simple 2-dimensional spring model. A vertical section through the layer with finite thickness is represented by a rectangular array of nodes connected by linear springs on a...
متن کاملModeling Evaporation, Shrinkage and Cracking of Desiccating Soils
ABSTRACT: Room temperature drying tests on silt slurry with free and constrained boundaries, reveal an initial phase with a significant shrinkage at full saturation. Hence, this shrinkage is linked to a mass loss of pore fluid through the external boundary. Shrinkage in the unsaturated phase is much smaller. A simultaneous porosimetry reveals a bi-modal pore size distribution with a distinct ev...
