摘要
双戗堤立堵进占截流过程中，其龙口水力参数的变化不仅与被截河段的地形条件、来流条件及导流建筑物的泄流能力等有关，而且与两道戗堤所处的位置及其布置形式有关。本文通过对各种戗堤布置形式龙口水力特性的分析，推导出各种布置形式的水力参数计算公式，并经模型试验验证具有较高的精度。
in the river closure using two embankments, the flow characters depend not only upon the geology, the topography,the hydrology and the diversion conditions, but also upon thepositions of the banks. Based upon a number of model tests, the flow characters, which can bedivided into three different types on the arrangement of the banks, are discussed in this paper.Inaddition, some formulae for the hydraulic calculation for each type are derived, which are provedto agree well with the test results. The research results are useful in the design and constructionof the bi- or multi-embankment.
