Scoping prediction of re-radiated ground-borne noise and vibration near high speed rail lines with variable soils

Numerical modelling of ground-borne noise and vibration in buildings due to surface rail traffic

This paper deals with the numerical computation of the structural and acoustic response of a building to an incoming wave field generated by high-speed surface railway traffic. The source model consists of a moving vehicle on a longitudinally invariant track, coupled to a layered ground modelled with a boundary element formulation. The receiver model is based on a substructuring formulation and...

A numerical model for ground-borne vibrations and re- radiated noise in buildings from underground railways

An efficient and modular numerical prediction model is presented to predict vibrations and re-radiated noise in buildings due to metro trains. The approach comprises of three weakly coupled problems: the dynamic vehicle-track-tunnel-soil interaction problem, the dynamic soil-structure interaction problem and the calculation of the acoustic response inside the rooms. The three-dimensional dynami...

Ground-borne vibrations and re-radiated noise in buildings from underground railways

Floating 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 ...

Vibrations and re-radiated noise in buildings generated by surface high-speed train traffic

This paper deals with the numerical computation of the structural and acoustic response of a building to an incoming wave field generated by high-speed railway traffic at grade. The source model consists of the model of a moving vehicle on a longitudinally invariant domain coupled to a boundary element model of the underlying ground. The receiver model is based on a substructuring formulation a...
