NOTE: This exam is divided into** 8 **pages. At the bottom of each page is a button that submits your answers for the current page. You must use this button to enter your scores to the database. Clicking on the forward and back buttons of your browser or using one of the links shown above does NOT submit your answers.

At the end of this exam you will encounter a confirmation page that lets you either finish the exam or go back to page 1 so that you can cycle through all of the pages again and review your answers.You can loop through the pages as many times as you want as long as you finish the exam on time.

1. (1.5 pt each) True or False:

a. T F (slope-reinforcement) When simulating

reinforcementin a slope stability analysis, the reinforcement forces input to the analysis are allowable forces and are not divided by the factor of safety prior to the computations.b. T F (slope-limit equil) With the

Bishop's Simplified Procedure, we must solve for the factor of safety iteratively.c. T F (slope-limit equil) The

Ordinary Method of Slicesis a complete equilibrium procedure.d. T F (slope-limit equil)

Spencer's Methodis a complete equilibrium procedure.e. T F (slope-reliability) With respect to the

3-sigma ruleused in reliability analysis, studies have shown that even experts tend to under-predict the range in parameter values (max-min). However, this is conservative because it leads to a smaller estimate of reliability.f. T F (slope-imp details) When doing an

infinite slope analysiswith a homogenous purely cohesive soil, the critical depth will alway be at the base of the layer (top of bedrock).g. T F (slope-seismic) When performing a

seismic analysis, the acceleration multiplier used to compute the k term is used to increase the peak acceleration because the acceleration is typically based on the bedrock and the acceleration at the ground surface is typicallyh. T F (slope-causes)

Lateral spreadsgenerally occur on steep slopes.i. T F (slope-shear strength)

Effective stressis equal to the total stress plus the pore water pressure.j. T F (slope-shear strength) When conducting the consolidation stage of a

CD or CU triaxial shear teston a soil, the time required for consolidation to occur is inversely proportional to the hydraulic conductivity of the soil.
