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 کاملcyclic behavior of mixed clayey soils
mixed clayey soils occur as mixtures of sand (or gravel) and clay in widely varying proportions. their engineering behavior has not been comprehensively studied yet. an experimental program, comprising monotonic, cyclic, and post-cyclic triaxial tests was undertaken on compacted clay-granular material mixtures, having different proportions of clay and sand or gravel. this paper presents the res...
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 کاملbehavior of clayey soils mixed with tire chips
recently, mixtures of clay-tire chips are used as construction material in civil engineering projects. with respect to the tending for using these materials, it is necessary to know their mechanical behavior. thereby, a number of undrained monotonic triaxial tests are carried out on the specimens of pure clay and clay-tire chip mixtures. mixed specimens prepared by mixing pure clay with 10%, 20...
متن کاملFinite element/percolation theory modelling of the micromechanical behavior of clayey soils
A hybrid model for soils, which combines percolation theory and finite element method is presented. The internal soil structure is modelled via the finite element method, and percolation networks are used for analyzing its mechanical behaviour. Through a microscopic characterization of elastic properties of soil grains, the model is generated. The effective percolation threshold obtained is low...
