Strain - ANSWER-An alteration in the shape or volume of a soil related to stress. It is calculated as the ratio of the new shape compared to the original shape Effective Stress - ANSWER-The total amount of stress placed on a soil minus the pore-water pressure Normal Stress - ANSWER-The component of total stress that acts perpendicular to the plane. Shear stress - ANSWER-The component of total stress that acts parallel to any point in question. Dilatancy - ANSWER-Tendency of a materia...

Early engineering works (1900s) assumed that rock was infinitely strong (T/F) - answer-True What is the name of the phenomenon, typical of very deep mining, that describes rock effectively "imploding" in the excavation? - answer-Rockburst Photo-elasticity was used in the early days of rock engineering to look at how stresses were redistributed around an excavation. In terms of mechanical behaviour of rock masses, what was the underlying assumption of that technique. - answer-Rock masses ...
