A multidisciplinary geophysical and geotechnical investigation of quick clay landslides in Sweden
2013 (English)Conference paper, Abstract (Refereed)
Landslides are one of the most commonly occurring naturaldisasters. They claim hundreds of human lives and costbillions of dollars every year. In order to providegeophysical tools and techniques to better characterize sitesprone to slide, we have been carrying out and evaluatingpotential utility of several geophysical surveys over a quickclay landslide site in southwest Sweden since 2011. Themeasurements include 2D and 3D P- and S-wave highresolution surface seismics, radio- and controlled-sourceelectromagnetics, geoelectrics, ground gravity andmagnetic surveys. A particular focus here is given to theseismic studies in the site. Combined with downholegeophysical and geotechnical measurements, we show thatmajority of reflections correlate well with sandy-siltyformations in the site. Quick clays often occur above theseformations, which may be an indication of the role ofcoarse-grained formations to not only partly form quickclays but also triggering them when pore-water pressure issignificantly increased.
