以Froude准则为基础，适当提高模型流速，在不同水位下进行了某侧向进水泵站的模型试验。结果表明：原方案前池内无论是面层还是底层，均出现大尺度回流区；水流斜向进入进水池，边侧水流偏斜尤为严重；翼墙回流区内流速较低，易造成泥沙淤积，对泵站的安全、经济运行不利。通过对底坎、导流墙、“Y”型导流墩等多种整流措施进行试验，发现采用由“Y”型导流墩演变而来的“丁”字型倒流措施能取得较好的整流效果。

Based on Froude rule, test on a side-inlet pumping station model was conducted with increasing velocity of flow properly. The results showed that: the original scheme would cause a wide range of circulation in the surface layer and bottom layer of the forebay；the side flow deviated badly when the oblique flow get into the intake sump; it would cause sediment deposition easily if the velocity of flow in wing wall’s circulation area was too low. It was bad for safe and economic operation of the pump station. Several measures were used to regulate the flow pattern, including bottom sills, diversion walls, “Y” type diversion pier and “T” type diversion pier which was a variant from the “T” type. The flow pattern could be obtained best with “T” type diversion.
