引大入秦景泰段输水工程渠系建筑物选择及其水力计算

Selection and Hydraulic Calculation of Canal System Buildingsof Water Conveyance Project into Yindaruqin in JingTai

结合引大入秦延伸增效景泰段输水工程的建筑物选择,在不同工况条件下,进行渠道及渠系建筑物的水力计算,特别是系统有富裕水头时,将富裕水头按流量增加合理分配,可使倒虹吸工程在多种工况下均能平稳高效运行,为类似工程提供计算思路。

Based on the selection of Yindaruqin Project in Jingtai,to demonstrate the hydraulic calculation results of canals and canal system buildings under different operating conditions.Especially the system has a surplus water head,the surplus water head is reasonably distributed according to the increase of flow rate,so that the inverted siphon project can operate smoothly and efficiently under various working conditions.This paper provides a calculation approach for similar projects.
