The cone penetration test (CPT) and, its geophone-equipped form, the seismic cone penetration test (SCPT) are increasingly used site investigation techniques to determine in-situ geotechnical properties of soil profiles as well as liquefaction susceptibility in seismically active locations. The use of experimental techniques, most notably miniature cone penetration testing (MCPT), can be used to recreate these in-situ tests in a controlled laboratory setting.
In this study, MCPT tests are completed using Fraser River sand to determine cone tip and sleeve frictional resistances as well as shear wave velocity measurements and are validated using in-situ SCPT tests and existing soil classification charts. Additionally, cyclic direct simple shear (CDSS) tests are performed to determine the cyclic resistance ratio (CRR) of the soil for ready comparison to existing liquefaction triggering correlations. Liquefaction events from laboratory testing results were found to compare reasonably well to various existing triggering curves reviewed in this study.
