Determination of Optimum 'Multi-Channel Surface Wave Method' Field Parameters.

摘要

Multi-channel surface wave methods (especially the multi-channel analyses of surface wave method (MASW)) are routinely used to determine the shear-wave velocity of the subsurface to depths of 100 feet for site classification purposes. Users are aware that the output shear-wave velocity function at a specific site will vary if acquisition parameters (including array orientation, geophone spacing, shot-to-receiver offset) are varied. However, these variations have never been statistically analyzed (quantitatively or qualitatively). As part of this investigation, the researchers will acquire MASW data at multiple study areas in karst terrain with a view to statistically analyzing the extent to which variations in field parameters can affect data quality, data utility, the output shear-wave velocity function and the output site classification.
