Influence Of Ground Railway Traffic Induced Vibrations On Surrounding Environment

With the development of social economy and improvement of science and technology, the vibration nuisance becomes an issue of great concern. In this thesis, the propagation of train-induced vibrations in the surrounding environment and their influence rules were systematically analyzed on the basis of previous achievements of relevant researches.Firstly, this paper introduces the theory of vibration, then the propagation of train-induced vibrations in free field was studied by using numerical method. The train types, train speed, the irregularities of track, properties of soil, distance to the road, the combinations of train were analyzed, respectively. Lastly, numerical simulation was employed during the study about the influence of train-induced vibrations on surrounding buildings too. Factors that can effect the vibrations were analyzed by the numerical simulation.Meanwhile, the effects of rail track structure optimizing and trenches on vibration isolation were also preliminary discussed. Some useful conclusions were drawn from these efforts.
