OCEN 674 Port and Harbor Engineering Design Homework Number 5 Fall 2007 A Team Design Problem 1. Using the U.S. Army Corps of Engineers program for calculating the forces on a sheetpile wall, analyze the maximum moment and where it acts according to the problem posed by Bowles in Example 13-6. Use his calculated depth rounded off to the nearest five feet. (Don't forget to use a Factor of Safety.) However, for this situation determine the location of the maximum moment and its magnitude if the depth on the seaward side is overdredged by 2 feet with a slope from the horizontal of 30 degrees. 2. Determine a suitable z section from steel from those commercially available for the bulkhead. Ignore the Rowe's moment reduction factor. 3. Use a graph and compare the moment and deflection for the free earth and the fixed earth method results for the overdredged case. 4. Why would you use the free earth method in this case rather than the fixed earth method? 5. Using the free earth method what size anchor rod would you use if you chose a 4 ft spacing? (Avoid the use of any high strength steel.) 6. What size continuous anchor would be required to carry the load and where should it be located? (Include only the passive resistance to the anchor.) 7. Design the sheet pile wall, including the depth, if you know that the water depth on the seaward side will fall by 6 ft during a low tide condition. Do not assume that a weep hole will suffice. .
