Summary
Experimental investigations are the basis for the understanding of the soil mechanical and hydraulic properties of unsaturated soils. The requirements for the testing and measurement equipment are relatively high. Important for planning the test procedures and the development of new testing devices is having experience with saturated soils and having carried out tests under simplified conditions. In this paper, basic knowledge of soil mechanical properties of saturated fine grained and non cohesive soils are reconsidered to include some basic considerations into unsaturated soil models. The aim is to incorporate the state parameters of sand and the equivalent stress of fine grained soils. For this reason some modified approaches are presented and requirements for further experimental investigations are specified.
