THE CURRENT STATE OF SOIL MECHANICS MODELS

Abstract

When designing geotechnical structures, there is a need to adopt a particular model to represent the soil we observe under a particular load. The parameters we set for this soil are sometimes incomplete, which is caused by various problems such as incomplete data from laboratory or field research. The choice of the correct model depends on how accurate the calculation we want to get, or how much risk plays a role for us and to what extent we can accept some solutions that do not give a true picture of soil behavior under load. That is why the proper model selection is the first step in solving geotechnical problems, on which all further work will depend.
