A method for determining the main mechanical properties of soft soils at high strain rates (10(3)-10(5) s(-1)) and load amplitudes up to several gigapascals

A new method has been developed for determining the main laws of the deformation of soft soils under conditions of dynamic loading with amplitudes of up to several gigapascals. The method is based on the results of high-strain-rate tests under uniaxial deformation conditions, which were obtained using a modified Kolsky method and the plane shock wave technique. The possibilities of the proposed method are illustrated by determining the dynamic properties of sand. (C) 2005 Pleiades Publishing, Inc.
