Vibration from underground trains: development of a prediction tool and the associated research
Ground-borne vibration generated by underground trains is a serious concern for inhabitants of buildings in close proximity to underground railway lines. Vibration is generated at the wheel-rail interface due to irregularities of wheels and tracks, and propagates to nearby buildings where it causes annoyance to people and malfunctioning of sensitive equipment. The problem can be very serious in some circumstances, for example when a railway line passes below a sensitive building such as a recording studio or a concert hall.
This presentation will review the developments of Pipe-in-Pipe (PiP) model for calculating vibration from underground railways. The presentation will focus on the extension of model to do fast calculation of vibration from tunnels embedded in a multi-layered half-space. This is an important development from the original version which used to do the calculation for tunnels embedded in a full space only.
The presentation will also highlight other associated work on the topic of vibration from underground trains, namely: centrifuge modelling of ground-borne vibration; modelling of inhomogeneity and non-linearity of railway tracks; modelling vibration from floating-slab tracks with discrete slabs; modelling ground-borne vibration as an evolutionary random process; the use of sub-modelling technique to couple a building to PiP; and developing an holistic approach for the design and assessment of railway tracks.
