Abstract: The method of dynamic compaction is one of important methods for ground treatment, the dynamic compaction to evaluation of dynamic compaction vibration effect, the basis of the evaluation are dynamic. This article takes the Changping District ridge village site as an example, through the landfill site for dynamic compaction vibration monitoring, analysd the dynamic compaction vibration amplitude and attenuation law of frequency, and the four polynomial representation field medium attenuation index. In field medium action spectra and dynamic excitation spectra based on, obtained by calculating the dielectric function and dynamic excitation function. Through the continuous accumulation of dynamic compaction vibration data, set up different properties of rock and soil and ground medium function relationship, then clearly engineering rock soil physical and mechanical properties and the dynamic performance between constitutive relation.
