李家河供水工程为长距离有压重力输水管道工程。为减小管末端静水压力及水锤压力，将管道分成2段，在每段末端设矩形调节池，调节池兼消力池。对矩形长调节池的消能做了水力学模型试验，以观察流态，实测最大流速及真空度、检验效能效果，最后提出调节池的尺寸等方案，并对矩形长调节池与圆形池比较，其结果可供同类工程参考。
李傢河供水工程為長距離有壓重力輸水管道工程。為減小管末耑靜水壓力及水錘壓力，將管道分成2段，在每段末耑設矩形調節池，調節池兼消力池。對矩形長調節池的消能做瞭水力學模型試驗，以觀察流態，實測最大流速及真空度、檢驗效能效果，最後提齣調節池的呎吋等方案，併對矩形長調節池與圓形池比較，其結果可供同類工程參攷。

The Lijiahe water supply project features the long pressure water transmission pipeline by gravity.To minimize the static pres-sure and water hammer pressure at the pipeline end, the pipeline is divided into two sections.One rectangular regulation tank is provided at the end of each section.This regulation tank is also the stilling basin.The energy dissipation of the long rectangular regulation tank is tested through the hydraulic model to observe the flow regime, measure the maximum flow velocity and vacuity, and verify the energy dis-sipation effect.Finally, the size of the regulation tank is proposed as well as the rectangular and the round regulation tanks are compared. The results provide reference to the other similar projects.
