Abstract : The U.S. Army Corps of Engineers is presently reanalyzing the stability of many of their concrete gravity dams due to new flood loading design requirements. Past practice has been to use to same stability criteria for reviewing existing structures as is used for designing new structures. Using the existing U.S. Army Corps of Engineer guidelines and conservative design parameters for cohesion, shear strength, and uplift, many of these dams have been determined to be unstable under the new design loads and will require expensive rehabilitation. A more realistic analysis of the stability of many of these dams could result in considerable cost savings for rehabilitation. (MM)
