Abstract

Investigation on the VOLUME CHANGE behavior of sands is one of the most important issues in Geotechnical engineering. Formulation and mathematical MODELING for prediction of the stress –strain and strength of soils under various stress conditions, especially saturated sands under cyclic loading, requires a profound understanding of the VOLUME CHANGE behavior of soils. Despite having many apparent advantages, most of the behavioral models developed by researchers loose their efficiency in predicting soil behavior in UNLOADING path. In this paper, after presenting discussion on the VOLUME CHANGE mechanism, it is shown that the total VOLUME CHANGE in GRANULAR SOILS can be divided into 3 different components. For each of the component, a new and rational relation is introduced; the sum of which is considered as the total VOLUME CHANGE under loading or UNLOADING condition. In order to investigate the variation of stress ratios and stress-dilatancy under triaxial loading conditions, a new comprehensive model is introduced using the new VOLUME CHANGE relation mentioned above. The accuracy and efficiency of the proposed model is examined by comparison of the experimental results on sands available in the literature and those predicted by the present model. It is shown that the proposed model predicts well the soil behavior under various stress or sand density conditions.
