In researching field conditions that would warrant an undrained total stress analysis, I’ve come across an example that perplexes me. This quote is taken from a technical report (verbatim):
“When the sediments are unloaded, such as occurs when a mine slope face is excavated, the reduction in...
I'm fishing for some advice or a format in creating a "living document". I work for a small firm and typically do 1 and done projects. After the report has been submitted, our work is typically done with the exception of an occasional questions or miscellaneous issue. However, I'm now...
I'm interested in your thoughts on how to locate the position and depth of a tension crack in a method of slices/limiting equilibrium computer analysis. The various programs offer lots of latitude in deciding how/where a tension crack is modeled. I've come across a few schools of thought on...
I'm interested in collecting core samples from the surface, without using a drill rig, for triax testing. Details on collecting the sample and extruding it to ultimately get an undisturbed and testworthy sample would be appreciated.
Thanks
I'm looking for an industry standard type of reference, from a government agency or professional organization (not necessarily US based), that provides ground support standards for underground metal mining. I know that support varies by ground conditions and the requirements of the excavation...
Today, a group of us mourn the loss of a colleague who was killed in a collapsed trench excavation about a year ago. My point of posting this thread is not to divulge details about what happened, but rather to send a shock throughout the geotechnical engineering community. Please do not ask me...
