THE INFLUENCE OF TRAIN-INDUCED GROUND MOTION IN ASSESSMENTS OF DYNAMIC IMPACT ON STRUCTURES

摘要

In this study, the issue of intensity of cargo train-induced soil vibrations is presented. Oscillations were measured in Warsaw-Rembertow location with application of set of seismic receivers. The analysis concerns the ground vibration differentiation issue, depending on considered direction of oscillation propagation plane. Statistic distribution of vibration intensity for directions in 3-D space were done. The issue of potential effect on engineering structures of recorded vibrations was raised. The impact based on Scale of Dynamic Effects standard was estimated in the article. Vibration intensity results were also compared with classification according to the Swiss Standard.
