PhD Student Awarded Best Presentation at EUROCK

Congratulations to Bradley Forbes, current PhD student under the supervision of Dr. Nicholas Vlachopoulos and Dr. Mark S. Diederichs, who has been awarded best presentation at the ISRM (International Society for Rock Mechanics) Regional Symposium EUROCK 2015 & 64th Geomechanics Colloquium held in Salzburg, Austria.

The paper/presentation titled “Monitoring the ground in order to optimize support design” was elected from all parallel sessions at the conference, which was held from the 7th-10th of October, 2015. This talk discussed the recent development and application of a distributed optical strain sensing technique for monitoring the response of temporary support elements (e.g. rock bolts, forepoles, steel-sets) used in underground excavations. Unlike traditional monitoring techniques, which provide a set a discrete measurement points along a instrumented support element (e.g. foil-resistive strain gauges), the optical technique is capable of capturing strain at a sub-centimeter spatial resolution along  the length  of a low-cost optical transducer (i.e. measurement locations every 1.25mm). This has allowed for support-ground interactions and complexities to be captured at an unprecedented degree. The optical technique is currently being used at the testing facilities in the Civil Engineering department at the Royal Military College of Canada and is being further developed as a “forecasting” tool for predicting ground behaviour ahead of the excavation face.

Congratulations Bradley!
