Dr. Ghazvinian specializes in geomechanics of brittle rocks. He offers expertise in continuum and discontinuum modeling of underground excavations prone to brittle fracturing and spalling. He has experience in application of numerical models to sequencing life of mine simulations and predicting potential seismic hazards in deep underground excavations.
FLAC3D TMis a numerical modeling code for advanced geotechnical analysis of soil, rock, and structural support in three dimensions. FLAC3D is used in analysis, testing, and design by geotechnical, civil, and mining engineers.
This FLAC3D V7.0 training course accommodates new and experienced users. It will be based on examples that attendees will develop and run by themselves to better grasp the mechanics of using FLAC3D V7.0, the key underlying calculation principles and the spectrum of available features. Attendees are encouraged to bring one of their specific cases that may be discussed.
The upcoming 70th annual Highway Geology Symposium will be held in Portland, Oregon, October 21st through October 24th, 2019.
Ms. Zetterlund is Itasca’s Training and Education Coordinator. Judy coordinates Itasca Consulting Group trainings; introductory trainings each spring, more focused trainings in the fall, and customized trainings upon request.
Hydraulic testing using wireline deployed water-inflated packers is becoming a common practice for groundwater characterization at mining sites. Packers, designed for diamond drilling, allow for faster, deeper, and more accurate types of testing conducted concurrently with existing coring programs. Designing and managing these testing programs requires planning, flexibility, and consideration of available methods and equipment options. This presentation explores and provides critical examination of advantages and disadvantages of the following options: 1) single or straddle packer testing, 2) injection, shut-in, withdrawal or falling head techniques, 3) discrete interval or cumulative testing, and discusses design consideration for planning a testing program.
