摘　　要：龙溪口航电枢纽工程施工期不允许断航,且洪水流量大。根据枢纽布置、地形条件和施工期通航要求,采用束窄河床导流方式,分三期导流。通过导流与通航模型试验验证,临时航道内布置13孔泄洪闸方案,泄洪通道过流能力和临时航道通航条件均满足要求,有效解决施工导流与通航“两难”问题,提高施工工期保证率,顺利地推动龙溪口航电枢纽工程建设。During the construction period of Longxikou navigation power junction, navigation interruption is not allowed, and the river has a large flood discharge. According to the layout of the project, the topographical conditions and the navigation requirements during the construction period, the narrow riverbed diversion method with three stages is adopted.Through the verification of diversion and navigation model test, the 13-hole flood gate scheme in the temporary channel can solve the "dilemma" of construction diversion and navigation, balance the construction intensity of each stage, improve the guarantee rate of construction period, and smoothly promote the construction of Longxikou navigation power junction project.
