چکیده
In the content of this study, non-linear consolidation behavior of unsaturated soils was investigated. In this respect a non linear differential equation for consolidation has been proposed. This proposed differential equation and its solutions enlighten both the diffusive characteristics and the time rate of settlement of soils. Besides, this study also enables to perform the matric suction calculation which is the one of the most important parameter of unsaturated soils. Two types of unsaturated consolidation test, constant water content test and contro lled matric suction test were carried out, respectively. Theoretical and experimental results were compared and it was found that they are in close agreement with each other. It was also observed that the proposed method can be applied to the saturated soils.

This study focuses on evaluating the unconfined compressive strength (UCS) of improved fine-grained soils. A large database of unconfined compressive strength of clayey soil specimens stabilized with fly ash and blast furnace slag based geopolymer were collected and analyzed. Subsequently, using adaptive neuro fuzzy inference system (ANFIS), a model has been developed to assess the UCS of stabi...
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...

This research was performed to determine the efficiency effect of sedimentary environment of Kerman City area on soil structure bycomparing natural and reconstituted consolidation curves. In this regard, four different criteria such as sensitivity strength, stresssensitivity, Schmertman criteria and the result of the uniaxial compression test were used. The base of these criteria is to compare ...
