Testing Campaign

MASW

MASW - multichannel analysis of surface waves

 

  • T0: MASW on soil pristine condition to set impact force, number of geophones, geophones spacing (dx), source offset (X1) and non-dispersive frequency range.
  • T1: MASW across the 5X10 grid (2.5 m X 5 m) (no resonators, T1 settings)
  • T2: MASWs across the metabarrier (5x10resonators, T1 settings) for different resonators arrangements.
  • T3: MASWs across different metabarrier lengths (arrays of 5x4,5x6 and 5x8 resonators, T2 settings).
  • T4: MASWs across different metabarriers (always5x10resonators) varying the masses of the resonators.

SASW Testing

 

  • A signal analyzer should be used to collect and transform the receiver outputs to the frequency domain.
  • Data from forward and reverse profiles are averaged together.
  • A simple empirical analysis can be done to estimate the average shear wave velocity profile.
  • Source-receivergeometry is optimized in order to minimize body wave signal.

Hosting Facilities

EUROSEISTEST is a multidisciplinary European experimental site (e.g. Pitilakis et al., 2011) which is located in the Mygdonia valley about 30km to the NE of the city of Thessaloniki in northern Greece.
