摘要
低佛水跃作为中低水头水利工程中常见的形式之一,其消能与防冲问题一直是该工程面临的难题。消能率低、下游波浪大、岸坡易淘刷等问题对工程建设和下游河床稳定性造成较大影响。为此,在设计、施工和运营过程中,需要采取有效措施来解决这些问题。在设计低佛水跃时,应充分考虑消能问题,并采取合适的消能措施,只有这样才能保证工程顺利建设和下游的稳定运行。
Low Buddha hydraulic jump,as one of the common forms in medium and low head water conservancy projects,has always been a challenge faced by the project in terms of energy dissipation and erosion prevention.The problems of low energy dissipation rate,large downstream waves,and easy scouring of bank slopes have had a significant impact on engineering construction and downstream riverbed stability.Therefore,effective measures need to be taken to address these issues during the design,construction,and operation processes.When designing a low Buddha water jump,energy dissipation should be fully considered and appropriate energy dissipation measures should be taken.Only in this way can the smooth construction of the project and the stable operation of the downstream be ensured.
