ABSTRACT

In this paper the stiffness at small strains of selected cohesive soils from
Warsaw area was evaluated on the basis of two varied laboratory techniques, namely,
resonant column (RC) test and bender element (BE) test. Both methods have different
advantages and limitations and they are both increasingly popular. They are
powerful and common laboratory tool for determining the shear wave velocity (V_S)
and hence the small-strain shear stiffness (G_max) in soil. In this
respect, special emphasis was placed on a brief presentation of these two techniques,
together with some attempt to compare them. The values of G_max obtained
by the RC and BE tests were compared to study the effect of test methods. The
main intention of the authors was to provide some contribution to the routine
laboratory practice using resonant column and bender elements, with some insight
in the interpretation of the received results.

Key words: resonant column tests, bender elements tests, natural cohesive soils.
