- Bedding is one of the most prominent features of sedimentary rocks. Would you expect a difference in strength parallel and perpendicular to bedding? In what way? How would permeability be affected? ExplainProvide generalized comments on the hardness, soundness, and durability associated with the three basic categories of rock.A parameter m in the Hoek-Brown criterion indicates how the type of rock affects the criterion's strength. It is anticipated that the rock will be stronger with a greater value of m. Using the values of m provided in the question and comparing the peak compressive strengths of granite, rhyolite, and marble with each other, qu = 100MPa For marble (m = 7): peak compressive strength =? For rhyolite (m =17): peak compressive strength =? For granite (m = 25): peak compressive strength =?
- 1. Name and describe the engineering properties of some Rocks used in construction? 2. What is rock mechanics? Discuss the scope of application of rock mechanics in engineering geology.we were told that the sigma y going up the sign is supposed to be negative in rock mechanics. ( I am confused, can you explain please) and the formula given to us about txy' does have a negative sign. I try it before posting those questions to verify my answer but because of those sign answer are different.How do metamorphic rocks that form deep inside the Earth under ductile conditions get exposed to the Earth's surface? Hint: Discuss movement along faults.
