Investigation of Unstable Slopes and Wind Turbine Sites with Surface and Borehole Seismic Technologies: Case Studies

Surface and borehole seismic imaging with both P and S waves enhance site assessments and reduce risks at difficult and complex geotechnical sites. These technologies increase the effective radius of investigation of boreholes alone and provide improved site parameters such as dynamic elastic modulus. Case studies illustrate applications at a major road project on unstable colluvial slopes and at wind turbine sites on variable, voided calcareous soils with calcarenites.
