Abstract

The present invention discloses a design method of broad base low-vacuum practial weir. Said invention includes system design mentality, weir surface curve design, flood carrying capacity calculation method, finite element stress check calculation and technical economic comparison of new weir type and WES weir. The most key of said design includes three factors of flood carrying capacity, weir surface pressure and volume of dam body, and its concrete design calculation method includes two portions of body type designand discharge coefficient definition.

Description

technical field

[0001] The invention relates to a design method of a flood discharge and overflow dam, in particular to a design method of a novel wide-band low-vacuum practical weir. Background technique

[0002] The practical weir is one of the most important structures in dam construction, and it has the dual functions of retaining water and releasing water. Therefore, in addition to being safe and reasonable in structure, it must also have good hydraulic characteristics. The broadband low-vacuum practical weir is a new technology for flood discharge of dams in water conservancy and hydropower projects. The content involves the design of the most important structure in dam construction, which has the dual functions of retaining water and releasing water——practical weir.

[0003] For more than a century, hydraulic engineering experts from all over the world have proposed a number of overflow weir shapes, among which the most representative ones are the WES weir proposed b...
