Abstract
The use of seismic surface wave method in civil engineering applications (such as determination of locations of building and bridge foundations, railway and highway route) become common practice in recent years. It is because this method provides shear-wave velocity, a parameter that directly related to shear strength of the subsurface structure which is an important parameter in civil engineering. In this paper, we discussed accuracy of the surface wave method in identifying the subsurface structure having irregular dispersive characteristic. Numerical and field tests were presented. Results from the numerical and field tests showed excellent ability of the surface wave method in delineating the subsurface medium with irregular dispersive characteristic. Comparison of a field test to the borehole data confirmed the ability.
