一种由导流洞采用“龙翘尾”型式改建成泄洪洞的设计方法
摘要：
本发明涉及一种由导流洞采用“龙翘尾”型式改建成泄洪洞的设计方法，其特征是，该设计方法是将一种导流洞采用“龙翘尾”式改建成泄洪洞，通过在导流洞尾部增设竖井段、水平转弯段，使所述水平转弯段的水平高度高于所述导流洞的水平高度。本发明优点：通过该设计方法改建的泄洪洞，具有洞内结构简单，施工工艺容易操作；能够改善工作闸门受力；使下游的消能问题容易解决，降低了造价成本。
摘要（英）：

The invention relates to a design method for reconstructing a diversion tunnel into a flood discharge tunnel in a 'tail-raising' mode. The design method is used for reconstructing the diversion tunnel into the flood discharge tunnel in the 'tail-raising' mode, wherein, a vertical shaft section and a horizontal turning section are additionally arranged at the tail of the diversion tunnel so that the horizontal height of the horizontal turning section is higher than that of the diversion tunnel. The design method has the advantages that the flood discharge tunnel reconstructed by the design method has a simple structure, and the construction process is easy to operate; stress state of an operating gate can be improved; and the problem of downstream energy dissipation is easily solved, and the manufacturing cost is lowered.
