Microstructurally Related Model for Predicting Behavior of Unsaturated Soils with Double Porosity in Triaxial Space
نویسندگان
چکیده
The microstructure can have an important impact on the hydraulic and mechanical behaviors of unsaturated soil; therefore, it must be considered in constitutive models to enable accurate predictions soil behavior. This paper focused modeling soils that exhibited a dual porosity structure. Based assumption macro micropores contained double structure had different influences behaviors, effective degree saturation (Se) was selected as microstructural index. index implemented within Bishop’s stress-based approach Glasgow coupled (GCM) modified Cam-Clay (MCC) were adopted basic framework for development model. Typical samples low expansive, nonexpansive, collapsible with validate model’s performance, model performed well when compared experimental data isotropic compression, triaxial shear, wetting tests.

A Hyperbolic Model for Stress-strain Behavior of Unsaturated Soils
A new simple shear apparatus is fabricated which is capable of applying monotonic and cyclic load on soil specimens. A series of tests was conducted to study the pore pressures (or suction), volume change, and shear behavior of the soil samples with anisotropic consolidation pressure. The simple shear apparatus is capable of controlling as well as measuring pore-air and pore-water pressure in t...
متن کاملEstimation of Water Retention Curve for Unsaturated Fine Soils
In order to obtain the soil water retention curve of an unsaturated soil which is defined as the relationship between water content and suction, extensive laboratory tests are essential. These laboratory tests are usually costly and time consuming. Moreover, for most practical problems, it has been found that approximate unsaturated soil properties are adequate for analysis. Thus, empirical pro...

Shallow foundations are often situated on unsaturated zones above the groundwater table. In this study, the influence of rainfall infiltration on the settlement behavior of shallow foundations was investigated using numerical analyses. The numerical solutions were compared with experimental data from in-situ load tests. The relative importance of rainfall intensities and groundwater table posit...
