Probabilistic Barge Impact Analysis of the Upper Guide and Guard Walls at Marmet Locks and Dam

摘要

This report describes the probabilistic barge impact analysis for the upper guide and guard walls at Marmet Locks and Darn. The report covers the results from the scale model experiments and the statistical processing of experimental data. Tow distributions are developed for the improved fleet at Marmet Locks. Probabilistic barge impact analysis is performed for both the foundation supports and the precast concrete beams of the upper approach walls. Return periods for barge impact loads are developed for usual, unusual, and extreme load cases.
