摘要
近来,随着计算机技术的提高,出现利用计算机对跨河桥梁局部流场进行模拟并得出大桥设计壅水高度的方法。本文以扬州市文昌东路东延工程中的廖家沟大桥为例,介绍了采用"水深平均二维数学模型"进行壅水分析计算的基本方法和主要步骤,为防洪评价中的桥梁壅水计算提供新的计算模式。
A method of stimulating local flow field of river crossing bridge by computer, and obtaining bridge design backwater height is formed with improvement of computer technology recently. Liaojiagou Bridge in Dongyan Project located in Wenchang East Road of Yangzhou is adopted as an example in the paper. The basic method and main steps of analyzing and calculating backwater by Water Depth Averaged Two-dimensional Mathematical Model are introduced, thereby providing new calculation model for bridge backwater calculation in flood control evaluation.
