ConsoliTest - Using Surface Waves for Estimating Shear-Wave Velocities in the Dutch Subsurface

Abstract

ConsoliTest is a geophysical method for estimating geomechanical parameters of the shallow subsurface. The procedure is based on the MASW method (Park et al, 1999) and has additional verification and validation modules. The Dutch subsurface can consist of an alternation of very stiff layers and weak layers. In these types of soils many non-standard waveforms are generated, which cannot be inverted properly by using only the MASW algorithm. By describing two case-studies we explain the developments at TNO-NITG for creating a surface wave method designed for the Dutch subsurface.
