| 摘 要： | 分析了丁坝附近的水流结构及影响丁坝冲刷的主要因素,并在理论上对冲刷深度公式进行了初步分析与推导,利用数学软件MATLAB对现有的试验数据进行多元回归分析,建立了丁坝冲刷深度公式,并将其与已有的部分公式进行对比,用仅有的实测资料进行验证。结果表明文章给出的公式较规范公式更接近实际值。

| Abstract: | The structure of flow around spur-dikes and factors affecting the scour depth of spur-dikes are analyzed.Based on the existed experiment data,the formula of scour depth has been deduced superficially on theory and established ultimately by the multivariate regressive analysis with MATLAB.The present formula is validated elementarily in availability,the result of which is compared with that of other ones.It is concluded that the result by the formula given in this paper conform better to the real values than that stipulated in Codes. |
