Dear SoilModels community
Dear Prof. Masin / all
I want to know how HP model considers Ko variation for the following cases:
Ko with variation with OCR?
Ko determination related to loading and unloading stress path?
Please refer me relevant papers.
For oed compression, model will lead to K0 approximately equal to 1-sin phc.
For oed unloading, model will predict increase of K0 with OCR, however, this is parameter-specific and cannot be quantified using a simple formula. You have to simulate oedometric undloading test to see what K0 values the model produces.
