Abstract
Vibrations due to construction activities and the resultant oscillation and potential damage of adjacent structures is an important issue in soil dynamics. To prevent damage, the intensity of building vibration on the subsoil and also on the building must be predicted. In most application cases, empirical equations are used to estimate the intensity of vibration (in terms of peak vibration velocity). However, these equations normally do not take site-specific soil conditions into account, but consider an energy term dependent on the construction machine and the distance of the operating machine to the considered building. In the paper, building vibrations due to vibratory rollers are considered. First, empirical approaches from literature are described and compared. Then, a numerical simulation model is presented, which allows the determination of peak vibration velocities due to vibratory roller operation of the soil in the free field as well as of a footing. A parametric study is conducted which shows the effects of subsoil conditions (i.e. soil layering and soil stiffnesses) and footing dimensions on the vibration intensities at varying distances to the vibratory roller. From a comparison of free field and foundation peak velocities, also transmission coefficients from soil to footing are determined.
