Homework - XSLOPE LEM, Part 1
Solve the following problems using XSLOPE. For each problem, start with the standard Excel input template:
After preparing each set of inputs, launch the XSLOPE Google Colab notebook for stability analysis and upload your Excel input file and solve.
For each problem, perform an automated search using Spencer's method.
(a) Submerged slope.
Be sure to use total unit wt and model the external water using a distributed load. Assume the water is 10 ft above the top of the slope.
(b) Slope with surcharge.
(c) Slope with two materials.
Submission
Save a copy of the Excel template for each of the three problems and save a PNG of the solution with the minimum factor of safety. Zip up your files into a single zip archive. Upload your zip archive via Learning Suite.
