dc.description.abstractIn recent years, underground train-induced ground-borne vibrations have become an important issue in heavily populated areas. As they cause not only the material failure but also serious human health problems, various vibration countermeasures are proposed and examined to control the train-induced ground-borne vibrations. The objective of this study is introducing Dynamic Vibration Absorber (DVA) as an innovative countermeasure in ground- borne vibration control field. DVAs are implemented on the interior floor of a double-deck tunnel which divides the structure into two halves and where trains circulate through both of them. The analytical model based on the receptance method is employed to calculate the mean power flow radiated by a double-deck circular tunnel. The model describes the dynamics of the interior floor using the thin plate theory and considers the Pipe-in-Pipe (PiP) model to describe the coupled tunnel-soil system. DVAs are coupled to the interior floor and their efficiency in minimizing radiated vibration power flow is studied. The effectiveness of DVAs depends on the parameters like their masses, damping ratios, natural frequencies and positions. Therefore, the most favorable design of DVAs requires optimal parameters. Genetic Algorithm (GA) is employed in order to find the optimum parameters of DVAs.
