Reducing railway-induced ground-borne vibration by using open trenches and soft-filled barriers
A trench can act as a barrier to ground vibration and is a potential mitigation measure for low frequency vibration induced by surface railways. However, to be effective at very low frequencies the depth required becomes impractical. Nevertheless, for soil with a layered structure in the top few metres, if a trench can be arranged to cut through the upper, soft layer of soil, it can be effectiv...
متن کاملInfluences of Railway Track Geometry Parameters on Ground-Borne Vibration
One of the most important challenges in the development of urban railways network is the effects of railway vibrations on human and adjacent structures. Although various investigations into the sources of railway vibrations have been conducted, very few research works have been reported on the influences of track geometry parameters on the level of vibrations. This is addressed in this resea...

متن کاملFloating Track Slab Systems for Reducing Ground- Borne Noise and Vibration from Rail Vehicles
This investigation explores both the theoretical and empirical modelling of the dynamic performance of floating slab track systems used for reducing groundborne noise and vibration from rail transit systems. Accurately predicting the performance of floating slab track systems is important to the success of a new rail project. In general it has been observed that analytical and numerical models ...
متن کاملThe effect of railway local irregularities on ground vibration
The environmental effects of ground-borne vibrations generated due to localised railway defects is a growing concern in urban areas. Frequency domain modelling approaches are well suited for predicting vibration levels on standard railway lines due to track periodicity. However, when considering individual, non-periodic, localised defects (e.g. a rail joint), frequency domain modelling becomes ...
