丁坝局部冲刷深度计算问题探讨

Preliminary Study on the Calculation of Partial Pier Scour

分析了丁坝局部冲刷机理及其影响冲刷深度的各种因素 ,并对现有丁坝局部冲刷公式的研究成果进行了比较分析 ,从而在理论上提出了一种新的丁坝局部冲刷计算公式 ,为工程计算提供了方便。

The principle and impact factors of the pier scour and the result from other researchers for pier scour have been analyzed in this paper. Based on the analysis of these formula of the partial pier scour, a new formula has been provided, which is convenient for the further study on the engineering practice according to the new result.
