Abstract : This report summarizes the results of a research effort to develop probability-based methods for expressing the structural reliability of gravity monoliths at navigation locks and dams. Existing reliability analysis techniques for civil engineering structures were adopted to the specific details of navigation structures. Using site-specific data, evaluations were made for the reliability of a number of structures with respect to sliding, overturning, and bearing capacity. Four of these structures are located on the Monongahela River in Pennsylvania and one structure is located on the Tombigbee River in Alabama. Based on the results of these studies, conclusions and recommendations are made for the reliability evaluation of similar Corps structures and use of such results for prioritizing rehabilitation investment decisions.
