Due Wednesday February 21, 2007
1) You have identified a saprolyte (weathered granite) along a rock cut. Explain how it was formed. What geologic hazards can be related to that kind of geologic environment ? 2) An elevator shaft is to

Homework Assignment 9 (Due Monday April 9, 2007). 1) Assume that a rock can be modeled as a Maxwell material. A series of tests on identical rock specimens were performed such that in each experiment the strain rate was held constant. Sketch a family of s

Homework Assignment 10 (Due Monday April 16, 2007) 1) Consider the geometry of Figure 1b and two orthogonal joint sets with spacings S1 and S2 intersecting the vertical hole. Since the joint sets are orthogonal, their dip angles 1 and 2 are such that 1+2=

Rock mass classification
Introduction
During the feasibility and preliminary design stages of a project, when very little detailed
information is available on the rock mass and its stress and hydrologic characteristics, the
use of a rock mass classificati
