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 کاملNumerical and Experimental Investigation of Desiccation of Soil
Mechanisms of shrinkage and the conditions leading to cracking of drying soils are addressed. An elastic formulation of the hydro-mechanical drying problem is presented. It relies on the analogy which can be drawn between the desiccation process and thermo-elasticity. The validity of the analogy is discussed in the light of finite element simulations of air drying experiments on a rectangular s...
متن کاملReview and Classification of Modeling Approaches of Soil Hydrology Processes
To use soil hydrology processe (SHP) models, which have increasingly extended during the last years, comprehensive knowledge about these models and their modeling approaches seems to be necessary. The modeling approaches can be categorized as either classical or non-classical. Classical approaches mainly model the SHP through solving the general unsaturated flow (Richards) equation, numerically...
