本文综述了国内外关于桥渡导流堤的研究成果,并在大量试验研究的基础上,提出了桥渡导流堤的平面尺寸、堤长、堤头流速等因素的计算方法和公式。经过实桥观测资料验证表明,本文公式的计算结果与实测资料是相吻合的。作者认为本文的计算方法可供生产实践应用。 This paper summarizes the research results at home and abroad about the diversion dike of the bridge and on the basis of a large number of experimental studies, puts forward the calculation methods and formulas for the factors such as the plane size of the diversion dike, the length of the dike and the velocity of the dike. After the actual bridge observation data show that the calculation results of this article is consistent with the measured data. The author thinks that the calculation method of this article can be applied to production practice.
