Popis: | The paper presents a method of the stiffness modulus identification of the soil built-in embankment, tested by the Light Falling Weight Deflectometer ZFG-01. The identification was carried out on the basis of displacements recorded during impact test. It was assumed that nonlinearity of the ground was described by changing in time values of the dynamic stiffness modulus. The original calculation program, based on finite difference method which enables the description of wave propagation in cylindrical soil solid under impact load, was used. The sensitivity of the dynamic stiffness modulus of the ground in the process of loading and unloading was confirmed. |
