ABSTRACT
The paper presents the methods and devices used in measurements of shear wave velocity to estimate the initial shear modulus in overconsolidated cohesive soil. Both shear wave velocity and initial shear modulus depends on many factors, especially mean effective stress and void ratio. This paper presents in details the results obtained from the SCPTU and the bender elements tests. Tests were carried out on overconsolidated cohesive soils from Warsaw. Finally the paper presents original relationship between the shear modulus, mean effective stress and void ratio.
Key words: shear wave, shear modulus, bender elements, SCPTU, cohesive soils.
