Procedure for Predicting the Deterioration of Steel Hydraulic Structures to Enhance their Maintenance, Management, and Rehabilitation

摘要

The deterioration of elements of steel hydraulic structures on the Nation s lock system is caused by combined effects of several complex phenomena: loss of protective system, corrosion, cracking and fatigue, impact, and overloads. This report presents examples of deterioration of steel hydraulic structures. A method for predicting future deterioration based on current conditions is also presented. The report includes a procedure for developing deterioration curves when condition state data is available.
