| 摘要： | The primary goal of the study is to develop a procedure to predict scour depths in bedrock that accounts for both the hydraulic conditions at the bridge site and the bedrock's ability to resist erosion. A methodology for determining material erodibility resulting from the erosive power of water has been presented by Annandale (1993, 1995). He introduced a relationship between stream power and a geochemical material classification system known as the erodibility index. The report applies his findings to bridge scour analysis and presents an interim procedure for estimating bridge scour depths in bedrock and other materials defined by the erodibility index. |
