The measurement of the small strain shear modulus, Gmax is determined using the Multichannel Analysis of Surface Waves (MASW) method for two soft clay sites in Ireland. Gmax 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.
