Congratulations Rachana! Join the GSE, UACGS Student Chpater and the UAlberta Geotechnical Centre in congratulating Rachana for another award, the GSE CGS Paper Award. Rachana will be presenting the highlights of the upcoming paper presented at the The Canadian Geotechnical Society / La Société canadienne de géotechnique GeoMontreal Conference later this month! 📣 Presenter: Rachana Adhikari, E.I.T. Topic: Mitigating the MASW uncertainties and developing a new SPT energy-based data acquisition method for site investigation When: September 12, 5 PM Where: University of Alberta Club Cost: $10 Register through Groupize here: https://lnkd.in/gqwjbH6b Abstract: The Multichannel Analysis of Surface Waves (MASW) method is a non-invasive geophysical test used to determine the subsurface shear wave velocity (Vs) profile based on the dispersion phenomenon of surface waves. MASW offers complementary advantages to conventional geotechnical tests for being cost-effective, environmentally friendly, applicable in all soil types, and can provide continuous 2D profiles for a given site. This study explores the integration of the Standard Penetration Test (SPT) and active MASW methodologies by using the SPT hammer as a source of seismic waves (higher source energy), and further providing for site-specific correlations between Vs and material characteristics. The research focus lies in employing a new data acquisition method with a fixed source (SPT hammer) and moving geophones, differing from standard MASW roll-along data acquisition practices for 2D generation, which maintains the fixed distance between the source and the first/last receiver throughout the data acquisition process. A pilot study was conducted in Edmonton, Alberta for the validation of the proposed methodologies. The Vs and 2D profiles were generated for a distance of 15 m using the fixed SPT hammer as a source and 24(4.5 Hz) geophones. The obtained results and those from the standard roll-along method were found to be comparable. This research validates the viability of employing the SPT hammer as a source for active MASW tests with a new 2D data acquisition method. This integration can be a cost-effective and easy way to address the issues of localized information in SPT and the validation of active MASW results.

Congratulations Rachana! We are excited to hear your presentation on September 12, at our joint event with the UACGS and UAlberta Geotechnical Centre. More details of Rachana’s presentation to come shortly!

#SundayFunday is a big one this week - #OTD 88 years ago, this group gathered in Cambridge, MA for the First International Conference on Soil Mechanics and Foundation Engineering - the event that would spur the creation of International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) and its national societies around the globe! Spot as many Geo-Legends as you can and put them in the comments!

We had the pleasure of hosting Dr. Ellen Rathje from the Fariborz Maseeh Department of Civil, Architectural and Environmental Engineering, The University of Texas at Austin for the Spring 2024 CCLT last night where she shared her insights on regional seismic assessments and the benefits of data sharing to better the global natural hazards community. Thank you for visiting Edmonton's geotechnical community! We presented Dr. Rathje with a piece of artwork by local artist Bee Waeland (IG: @beewaeland) as a token of appreciation. Dr. Rathje is presenting tonight at the Calgary Geotechnical Society (CyGS). #LetsGoOilers The CCLT is supported by the Canadian Foundation for Geotechnique and organized by the The Canadian Geotechnical Society / La Société canadienne de géotechnique. This season's CCLT sponsors include ConeTec, Klohn Crippen Berger, Reinforced Earth Company Ltd. - Canada, Thurber Engineering Ltd., TREK Geotechnical Inc. and WSP in Canada.

Don't miss the upcoming CCLT Lecture featuring Dr. Ellen Rathje this Wednesday! Register at Eventbrite link.
