The intensity of road & railway usage continues to increase. Traffic caused vibrations which migrate through the soil, possibly causing nuisance to residents. Such vibrations can even be a hazard to buildings, sensitive equipment or create pressure waves underneath railways.
Railways & other roads
The rail network is under pressure. The number, speed and weight of trains increases, causing more violent vibrations. Such vibrations cause nuisance.
BISI brings 2 ways to mitigate this:
At a pilot project in Toronto, Groundwater Technology create miniature earthquakes to verify the effects of gas bubbles on vibration propagation. A very large seismic testing machine was mobilized all the way from Texas to Toronto. This induces major vibrations to the subsoil, measuring wave propagation in real time. We found that presence of gas reduces wave propagation velocity by 75% as compared to wave propagation in fully saturated soils at the same site, outside of the treated zone.
