Micro-seismic measuring method to test the condition and the water content of the soil

The aim of these developments was to find such dynamic phenomena or signals, which can be used to forecast the impending landslide with a higher reliability than the static geodetic deformation measurements. The loess walls show no movements detectable by geodetic methods. For monitoring micro-deformation processes, since their sub-microscopic realm, dynamic measuring methods can be applied. Such kind of real-time systems give information about the evolution of the internal state of the slope and therefore a reliable event precursor could be obtained. The concept is the measurement and analysis of ambient vibrations on the loess wall to investigate the changes of the geotechnical parameters of the soil.
