Resonant-Column Testing—Problems and Solutions

Source

The resonant-column test is a relatively nondestructive test employing wave propagation in cylindrical specimens of soil and rock. Test results are usually quite accurate, but in some cases insufficient coupling exists between specimen and apparatus or specimens are too stiff for a given apparatus, or both. A criterion is given to evaluate whether a coupling problem exists and solutions are suggested. Procedures for evaluating limiting specimen stiffness and maximum strain amplitude capabilities are given. Solutions for reducing air migration problems during long-term tests are presented. Finally, a simple method for estimating strain amplitudes during a test is demonstrated for both shear and axial compression.
