Density-Dependent Pore Water Pressure Evolution in a Simplified Cyclic Shear Test

Abstract When specimens of different sands are produced using the same preparation method and sheared under conditions (consolidation stress, loading, etc.), while simultaneously keeping drainage closed, resulting tendencies these regarding PWP build-up will be different. This research paper presents a simplified cyclic shear test, which is used to evaluate accumulation in defined specimen procedure testing conditions. In proposed experiment, comparison with this respect easily achieved. The principle experimental based on evolution during shearing water-saturated sand sample. Undrained experiment allow for PWP, quantified by rate build-up. duration single including preparation, approximately 30 min. evaluation densities resulted an exponential dependence variation relative density. results confirmed higher generation fine compared coarse sand. A undrained triaxial tests case eight demonstrated good agreement between both methods. basis was density-dependent presented delivers value (index) that quantifies
