| 摘 要： | 嘉绍大桥河段潮大流急，是涌潮发展、壮大的河段，设计流速预测准确与否关系到桥梁工程施工和运行的安全，应用数学模型来预测设计流速是有效途径之一。应用基于Boltzmann方程的KFVS（Kinetic Flux Vector Spiting）格式，采用WLTF（Water Levelbottom Topograph Formulation）方法和特殊的底坡源项处理技术，实现了计算格式的“和谐”。模型在钱塘江涌潮验证的基础上，求得0．33％设计潮差频率条件下的桥位断面设计涨潮流速为7．83m／s，为桥梁设计提供了重要参数。

| Abstract: | The tidal bore develops and enhances at Jiashao Bridge river reach with the strong tide and rapid velocity.Accuracy of design velocity is very important to safety in the construction and operation of bridge works.Numerical model is an effective method for determining the design velocity.In this paper,a 2-D numerical model for the tidal bore in the Qiantang River was developed using KFVS(Kinetic Flux Vector Splitting) scheme based on the Boltzmann equation,with WLTF(Water Level-bottom Topography Formulation)... |
