# HW#16 - UTEXAS, Part 2

Use UTEXASED4 to solve for the critical factor of safety against slope failure for the following problem based on a circular failure surface (compare to page 121 in your textbook):

You will need to calculate the proper coordinates for your profile lines. Extend the problem 150 ft to the left and the right of the upstream and downstream toes of the dam. Use the given elevations for the y coordinates and let x=0 at the upstream toe of the dam. Please do your coordinate calculations in a spreadsheet so that I can easily check your calculations.

The material properties are as follows:

The coordinates of the piezometric line are as follows:

Be sure to include external loads to represent the water on the upstream side.

Use a circular failure surface. Perform two sets of calculations: one for the upstream side and one for the downstream side. The side that is analyzed depends on the locations of your starting circles.
