Abstract:
Soil Young's modulus (E), commonly referred to as soil elastic modulus, is an elastic soil parameter and a measure of soil stiffness. It is defined as the ratio of the stress along an axis over the strain along that axis in the range of elastic soil behavior. The elastic modulus is often used for estimation of soil settlement and elastic deformation analysis. Soil elastic modulus can be estimated from laboratory or in-situ tests or based on correlation with other soil properties. In laboratory, it can be determined from tri-axial test or indirectly from odometer test. On field, it can be estimated from Standard penetration test, Cone penetration test, pressure meter or indirectly from dilatometer test. The main hurdle in estimating the settlement for a desired structure is to identify the value of elastic modulus (E). As a lot of work has done for the calculation of elastic modulus but a proper estimation for elastic modulus has yet to achieve. Our basic aim is to increase our understanding of interaction between elastic modules and Soil Penetration Test value (N value), elastic modules and Cone Penetration Test value (qc value). We aim to achieve a relationship between D50 and elastic modulus for general granular soils We aim to make automated excel spread sheets for various Settlement methods proposed by different geotechnical Scientists and researchers by using elastic modulus of soil and their comparison with settle 3D.
