In Situ Characterization of Soils for Prediction of Stress-Strain Relationship

Abstract

A non-destructive method of characterizing particulate systems using electrical properties is presented. The application of this methodology for the demarkation of cohesive and granular soils is demonstrated. The significance of this approach is that electrical properties of soils such as conductivity, sigma, and dielectric constant, epsilon, as a function of frequency, can be measured in situ. These properties, when suitably interpreted, can be used to quantify the structure of particulate systems including the inter and intra cluster void ratios. These structural properties can then be correlated with mechanical properties such as k sub o, lambda, k and M. Incorporating these mechanical properties into a bounding surface plasticity model, the in situ stress state and in situ stress strain behavior could be predicted. Application of this method to mixed soils is demonstrated in this report. This approach therefore provides a non-destructive method of characterization soils for the prediction of mechanical behavior.
