At shallow depth, the initial stress state can significantly affect the behavior of the rock mass around excavations, but stress measurements are usually subjected to high levels of uncertainty. This was the case at the Odenplan railway station in Stockholm where unexpectedly large deformations were measured during the excavation.
The 56th US Rock Mechanics / Geomechanics Symposium covers all aspects of rock mechanics, geomechanics, and rock engineering.
Jim Hazzard is a geological engineer with a Ph.D. in geophysics. He has extensive experience in software development for geomechanics and he is currently the Software Manager at Itasca Consulting Group, as well as product manager and primary developer for 3DEC.
