I am trying to model soil using HS constitutive model in Plaxis, for which I am in need of soil parameters such as E50 ref, Eoed ref, and Eur ref. I have the UU triaxial test data without unloading and reloading and on the other hand I don’t have oedometric tests data.
I am looking for any correlations which can be used to determine these parameters. I have SPT N values, shear strength parameters c and phi from lab tests, GSD, and atterberg limits in hand. It will be helpful if someone can share any relevant details.
Dear Vijaya,
Nice to hear about your interest in finding hardening soil parameters. As you aware hardening soil parameters purely stress dependent and consequent change of volume to be considered. Therefore, you need triaxial test results to obtain E50, Eura. I don't think it is to be evaluated based on correlation with SPT N value. I have literature related to hardening soil model with complete guide book. But it is having larger memory almost 54 MB so unable to attach with this message. I may send through google drive later.. ok all the best..
Karthigeyan . S Thank you very much for your response, Sir. It will be of great help if you could send the literature.
Welcome ma..yes..it is possible to send via google drive only because memory of that file is 50 MB..so send your sample mail to my email id. [email protected]. I will send through mail..all the best..
For clay, you consider my article that correlates these values with the plasticity indices and the natural water content.
