| Abstract | Different relations between shear wave velocity and parameters obtained from seismic cone penetration tests are evaluated against a data set collected at 107 sites along the St. Lawrence River Valley in
Eastern Canada. Only sands or sand-like soils with a normalized SBT index Ic less than 2.60 and a normalized porewater pressure ratio Bq less than 0.10 are considered in this study. All investigated soils are approximately 7,000-12,000 years old and
are of a marine, mainly deltaic, origin. Correlations established for Holocene sands systematically under-predict shear wave velocities determined for the tested soils while the opposite is observed for correlation developed for Pleistocene sands.
Non-linear regressions and residual analyses conducted for the tested soils indicate that the best prediction model has a functional form incorporating the cone tip resistance, the sleeve friction resistance, and the effective vertical overburden
stress. A good correlation is also obtained with only the cone tip resistance and depth. As a result, two new equations are presented specifically for sands in the St. Lawrence River Lowlands which allow for an estimation of shear wave velocity based
on piezocone test data. This open-file report is an extended version of a paper presented at the 69th Canadian Geotechnical Conference in Vancouver (Perret et al., 2016). |
| Summary | (Plain Language Summary, not published)
This report is an extended version with additional figures and appendices of a paper that will be presented at the 2016 Canadian Geotechnical Conference
in Vancouver. Sand liquefaction induced by earthquakes can cause considerable damage to buildings and critical infrastructure. Liquefaction analyses requires to determine shear wave propagation velocities in these sediments. This article proposes
new correlations tailored to Eastern Canada sands 1) to estimate this parameter from geotechnical tests commonly used in professional practice, and 2) to identify possible errors in the determination of this parameter. |
