Metro Train-Induced Vibration Measurement on Buildings

Abstract

Vibrations in four buildings located at different positions along the Delhi Metro Rail Corporation (DMRC) network have been measured and reported. Vibrations developed due to the passage of metro trains through tunnels located at a depth up to 30 m from the ground level were measured on the considered buildings at different floor levels. To interpret the effect of vibrations on buildings, different vibration parameters, viz. Peak Ground Acceleration (PGA), Peak Ground Velocity (PGV) and frequency content are obtained from the recorded vibrations. These parameters change with the location, depending on the dynamic characteristics of the soil profile at the site of measurement and the building. It is observed that the maximum amplitude of vibrations measured during this study is more than the threshold provided by standards of different countries and can cause vibration of rigid building components, annoying physical sensations in the human body, interference with activities such as sleep and conversation, rattling of window panes and loose objects and fear of damage to the building and its contents.

Analysis of Vibration Responses Induced by Metro Operations Using a Probabilistic Method

“…The urban rail transit system, characterised by convenience and speed, has become one of the main ways of transportation for daily travel. However, the operation of an urban rail transit system may increase the environmental vibration level around the lines, bringing some adverse effects to workplaces and living environments [1][2][3].…”
