摘要
基于沿水深方向积分的平面二维水流运动方程组,在采用合理的假定条件下,推导出透水丁坝坝后回流区长度计算公式,研究结果表明,透水丁坝坝后回流区长度不仅与坝长、水深、糙率、面积缩窄比、河宽缩窄比等因素有关,而且与丁坝本身的渗流量有关。
Based on 2-D averaged difference equations and under proper assumptions, the calculation formula for the length of the circulating length of seepage spur dike was derived. The research result proves that the length of circulating region of seepage spur dike is not only related to dike length, water depth, roughness, and area contraction ratio, but also to seepage flow of dike itself.
