Abstract

The measurement of the small strain shear modulus, G_maxis determined using the Multichannel Analysis of Surface Waves (MASW) method for two soft clay sites in Ireland. G_max profiles generated using the MASW method compare very well with values derived empirically from CPTU data and also with results of laboratory triaxial testing. A synthetic earth model generated using a Discrete Particle Scheme (DPS) was also used to evaluate the software, Surfseis. The MASW method compares well with both the conventional seismic methods and the synthetic model.
