摘　　要：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.

关 键 词：渠系建筑物 倒虹吸管 水力要素 水头损失 纵断面优化设计
