为了验证井柱桩透水丁坝的分水缓流作用效果,建立单排井柱桩透水丁坝运行时的水量平衡方程,导出了单排井柱桩透水丁坝上下游流速公式。以塔里木河三号口断面建单排井柱桩透水丁坝为例,计算单排井柱桩透水丁坝上下游流速值并进行比较,结果表明,井柱桩透水丁坝下游流速较上游流速显著降低,与实际效果相符。 In order to verify the water diversion and slowing effect of wellbore piles, the water balance equation of single-well well post was established, and the formula of upstream and downstream flow velocities of single-row well post was derived. Taking the single row of well percolating pebble in Tarim River No.3 cross section as an example, the upstream and downstream flow velocity values ​​of percolating piles in a single row of well post were calculated and compared. The results show that the downstream velocity of permeable pylon in well post is obviously lower than the upstream flow rate, In line with the actual results.
