Abstract: The influence of the method of attachment of accelerometers to the ground on the recorded level of vibration accelerations is analyzed in the paper. Transducers were mounted to the ground in six different ways – using measuring bases in shape of a plate without any anchoring, anchored or not plate bases with an aluminum cylindrical heads, metal base rings with three pins, cross-bases with four pins and aluminum cylindrical heads and aluminum cylindrical heads buried at a certain depth in ground as well. In case of few measuring bases measurements were conducted using two types of accelerometers. The studies demonstrated that the method of attaching of accelerometers to the ground is crucial for the credibility of measurements. The best way of interconnecting transducers with the ground was shown in the paper. The resulting values of vibration acceleration may constitute a basis for a reliable analysis of the propagation of vibration in the subsoil, as well as support the development of methods of estimation of subsoil stiffness using surface seismic data.
