Abstract

Three widely-available surface wave measurement techniques, including two active-source methods, the Spectral Analysis of Surface Waves (SASW) method and the Multi-channel Analysis of Surface Waves (MASW) method, and one passive-source method, the Refraction Microtremor (ReMi) method, were applied at a complex-layered site. Dispersion relations were compared to one another. Outcomes from the MASW measurement reveal a fundamental and first-higher mode. All three methods agree closely in the frequency range over which only one mode is present. The dispersion curve from the SASW method, which represents a superposition of modes, shifts gradually from the fundamental mode to the first higher mode as frequency increases. The ReMi outcome tracks only the fundamental mode over its range of analysis.
