Evaluation of the multi-channel surface wave analysis approach fo rthe monitoring of multiple soil-stiffening columns
Many buildings are constructed on poor quality ground. A standard remedial action is to bore shafts and to fill these with rocks. The cost-driven desire is to sparsely space the piles whilst maintaining adequate ground stiffness. This is the first paper published showing the use of surface waves, acoustic sensors arrays and inversion techniques to assess the condition of the surrounding ground. This work resulted from a multi-University £3.5m EPSRC ‘Mapping-the-Underworld’ initiative (supported by 34 partners). The pioneering method developed provides non-invasive, quantitative feedback to an industry facing $1bn annual repair and replacement costs in the US alone.
