| 摘要： | This report evaluates the current state of knowledge regarding bridge-pier scour, assesses leading methods for reliable design estimates of scour depth, proposes a structured methodology for scour-depth estimation for design purposes, and indicates pier-scour aspects in need of further research. It focuses particularly on research information obtained since 1990, showing that this information provides considerable new insights that compel the need to change the design method currently recommended by the principal authoritative design guides (notably FHWAs HEC-181, and AASHTO2) and used widely by bridge-engineering practitioners. Additionally, it indicates that several important aspects of pier scour processes remain inadequately understood and not yet incorporated into design methods. |
