Abstract [en]

The chief target of soil stabilisation with the deep mixing method is to improve the strength and compression properties of soft soils. The determination of strength and of deformation moduli of stabilised soils in pre-testing in the laboratory can be performed in different ways. In addition to the unconfined compression test, which is the most commonly used method for routine testing, different seismic non-destructive methods may also be employed. In order to evaluate strength parameters from these methods, correlations between the wave velocity and the undrained shear strength are required. At the Swedish Geotechnical Institute, the unconfined compression tests performed in the laboratory have routinely been preceded by shear wave velocity measurements with bender elements in a large number of tests. The alternative method Resonant Column freefree test has also been used, in parallel, to determine the shear wave and compression wave velocities in the same test specimens. This has allowed comparisons to be made of the shear wave velocities obtained with the two tests methods. Fairly good and reliable relations between shear wave velocity and undrained shear strength have been established for stabilized clays of initial medium and high plasticity.
