摘要: Methods for determination of shear wave velocity (vs) with bender elements using frequency domain techniques are reviewed. An enhanced method is proposed, which quicker and provides more information than existing techniques. The can be implemented a spectrum analyzer—a common piece hardware. validity the demonstrated by means series bench top tests on reconstituted clay sample. results compared both practice established time-domain reveal that system comprising benders soil sample dispersive. relationship between in detail several propagation paths through sample, allowing some insight to gained into factors influencing dispersion characteristics.
