Method for ambient vibration analysis

Abstract

A method for determining ground properties of a sub-surface target volume is disclosed. The method comprises measuring ambient noise received from a plurality of surface wave sensors placed along a predetermined grid of locations around a surface of the target volume, the measuring is done with the plurality of surface wave sensors for a predetermined time period to produce noise data. The method also comprises defining a second grid of primary study locations around the surface of the target volume; for each primary study location in the second grid, determining a local Rayleigh wave dispersion curve using the noise data from a selected sub-array of the plurality of surface wave sensors, and concatenating the local dispersion curves for the primary study locations to provide a three-dimensional model of the sub surface properties of the target volume. Unlocking insights from Geo-Data, the present invention further relates to improvements in sustainability and environmental developments: together we create a safe and liveable world.
