| 摘 要： | 多年来，丁坝局部冲深计算大多局限在半经验半理论的回归分析计算方面，由于客观条件的不同，虽计算公式众多，彼此形式及结果也分歧较多。鉴于这种状况，根据流体力学原理、试验现象和数据，从理论分析出发，尝试性地提出了丁坝局部冲深计算理论公式，经与试验结果比较发现：理论公式的结构合理，与试验结果相符，从而为半经验半理论回归公式的进一步研究提供了理论方面的基础。

| Abstract: | The calculation of local scour depth of spur dikes is mostly limited in semiempirical and semi theoretical regression computation over the years.Though there are lots of calculation formulas,their forms and calculated results are quite different due to different objective conditions.In this paper,according to fluid mechanics principle,a theoretical analysis was made of experiment phenomena and data,and a theoretical formula was put forward to calculate the local scour depth.The calculated results are in agreement with experimental results,which shows that the structure of the formula is rational.The work in the paper provides a theoretical basis for further study of semiempirical and semi theoretical regression analysis. |
