涵管水力计算书

水力计算书本计算按照混凝土重力坝设计规范（SL319-2005）进行计算。计算公式：1、计算沿程水头损失系数：根据曼宁公式c =丄尺6, R = d/4，可计算得C, n则有：久=If式中 C 谢才系数，m于/S；n 糙率，在此取混凝土管糙率0.012；R 水力半径，m；d 管道内径，m；久沿程水头损失系数；g 重力加速度，取9.8m/s；2、计算流量系数：1c = I / = 少+4 +空式中 叫流量系数；久沿程水头损失系数；管道总长度；d 管道内径，m；局部水头损失系数，查表可得，= += 0.5 + 1.0 = 1.5。出口 进口3、计算过水能力式中 Q 流量，（m3/s）；化流量系数；A 过水断面面积，（m2）。g 重力加速度，取9.8m/s；H 作用水头（m）；4、水力计算表：水力计算表水位水深过水断 面水 力 半 径糙率局部 水头 损失沿程 水头 损失管道 长度内 径谢才系 数流量系 数流量备注HAHARn工Z入L (m)dC卩cQ37910.50240.20.011.50.019140.863.7270.59361.3203379.51.50.50240.20.011.50.019140.863.7270.59361.617138020.50240.20.011.50.019140.863.7270.59361.8672380.52.50.50240.20.011.50.019140.863.7270.59362.087638130.50240.20.011.50.019140.863.7270.59362.2869381.53.50.50240.20.011.50.019140.863.7270.59362.470138240.50240.20.011.50.019140.863.7270.59362.6407382.54.50.50240.20.011.50.019140.863.7270.59362.800938350.50240.20.011.50.019140.863.7270.59362.9524383.55.50.50240.20.011.50.019140.863.7270.59363.096538460.50240.20.011.50.019140.863.7270.59363.2341384.56.50.50240.20.011.50.019140.863.7270.59363.366238570.50240.20.011.50.019140.863.7270.59363.4933385.57.50.50240.20.011.50.019140.863.7270.59363.615938680.50240.20.011.50.019140.863.7270.59363.7345386.58.50.50240.20.011.50.019140.863.7270.59363.849438790.50240.20.011.50.019140.863.7270.59363.961387.59.50.50240.20.011.50.019140.863.7270.59364.0695388100.50240.20.011.50.019140.863.7270.59364.1753388.510.50.50240.20.011.50.019140.863.7270.59364.2784389110.50240.20.011.50.019140.863.7270.59364.3791389.511.50.50240.20.011.50.019140.863.7270.59364.4775390120.50240.20.011.50.019140.863.7270.59364.5738390.512.40.50240.20.011.50.019140.863.7270.59364.653139112.50.50240.20.011.50.019140.863.7270.59364.6681391.5130.50240.20.011.50.019140.863.7270.59364.760539213.50.50240.20.011.50.019140.863.7270.59364.8512392.5140.50240.20.011.50.019140.863.7270.59364.940239314.50.50240.20.011.50.019140.863.7270.59365.0277393.314.80.50240.20.011.50.019140.863.7270.59365.0708会龙池水库394150.50240.20.011.50.019140.863.7270.59365.1136394.515.50.50240.20.011.50.019140.863.7270.59365.1982395160.50240.20.011.50.019140.863.7270.59365.2813395.516.50.50240.20.011.50.019140.863.7270.59365.3632396170.50240.20.011.50.019140.863.7270.59365.4439396.517.50.50240.20.011.50.019140.863.7270.59365.5234
