Complete the values in table 1 and draw a Mohr circle for each compression test
5. For a concrete cantilever wall of the dimensions as in Figure 2 (y = 24 kN/m³)that supports back fill of the following characteristics: y = 21 kN/m³ and ø=36°determine the ultimate limit states (ULS) for: a. Overturning b. Sliding, assuming the angle of friction on the base & = 25 c. The maximum and minimum bearing pressures beneath the base of the wall
Brittle deformation results in faulting. The type of fault produced depends on the type of stress applied to the rock. In the animation Faults e, select the 'Types of Faults" menu and watch each part (link also in Week 6 Preparation on Canvas). Use the information from it to label the four images below with the appropriate name for the type of fault shown.
A stratovolcano recently erupted in the United States. Although it warned of its impending eruption, it still killed people, partly because it first blew sideways and produced a monstrous landslide. The volcano is A. Mt. Rainier. B. Mt. St. Helens. C. Yellowstone. D. Surtsey.
Many different processes occur within a rack when it experiences metamorphism. The following animation is a good introduction to the main types of metamorphic change. Watch the animation on Metamorphic Change e (link also in Week 6 Preparation on Canvas) and then click through the topics and watch each one. Match each of the fallowing processes with the paper description.(Note: In the animation, plastic deformation is described in both the compression and shear segments.)
Bowen's reaction series A. was established by laboratory experiments. B. shows the sequence in which different sulfate minerals form during the progressive cooling of a melt. C. has a discontinuous track in which a progressive change with decreasing temperature is observed, from calcium-rich to sodium-rich plagioclase. D. creates a progressively more mafic melt.
A large civil engineering project is to be conducted in an area where the ground is mainly dominated by limestone. Briefly describe the parameters that need to be considered to assess the rock mass quality of the Limestone . Comment on the influence of each of these parameters on the rock mass.
Identify the rock samples A and B shown in Figure 3. Compare and contrast the two rock samples in terms of their formation and engineering properties. How can these rocks be used by engineers and what problems can we expect?
Intrusive igneous rocks A. cool slowly and are coarse-grained. B. are rocks like basalt, andesite, and rhyolite. C. are fine-grained because they cooled slowly. D. are never seen by humans, because they form deep in the Earth and are never exposed at the surface.
8. Is the area you chose part of a debris flow? Is any area near you? (After you've done this uncheck the "Debris Flow" box)
