T1 - The influence of soil properties on the ground vibration due to railway traffic and other sources - the comparability of different sites N2 - If ground vihrations are measured at different siles, the soil properties may be different even if the two sites are close together. Thcrefore, it is necessary to determine the soil properties of both siles to eliminate a possible influence of the soil. The contribution presents the methods of measuring the dynamic soil properties, wave velocities in time histories, dispersion by SASW, SPAC and F-K evaluation methods, identification of the soil profile, material damping, and Transfer functions. These methods have beeil applied mainly for train induced Vibration and to assess the effecl of different railway tracks, elastic or stift' track elements, damages or repair of railway tracks, or the influence of train speed. Sonic exainples are given to demonslrate the evaluation of the layered soil profiles and how strong different soil properties can interfere with the evaluation of any projected improvenienl. Diffcrenees of soil properties should be takcn into account even for a single measuring site and the ground Vibration should be. measured on a line of measuring points which is usually also necessary for the indispensable determination of the soil properties.
