山西省离石县改河扩城工程中消力池选型及其设计

Type selection and design of stilling basin in river cutoff project in Lishi county, Shanxi province

结合山西省离石县改河扩城工程中消力池的选型试验，提出了几种消力池体型。根据稳定水流的能量方程及动量方程，导出了矩形明槽中消力池的计算式，并用该工程的试验结果进行了验证计算，计算结果与试验资料基本吻合。

ased on type selection of stilling basin for the river cutoff project in Lishi county, slope types of stilling basin are presented in this paper. Formulas with which the size of stilling basin of rectangular open channel can be calculated are also derived in this paper based on energy equation and momentum equation of steady flow. Fair agreement between calculated values and test results for Lishi county river cutoff project is obtained after verification.
