Abstract: 用MIKE21水动力模块和物理模型对三里埂汇流段流场进行了模拟.经过试验验证,模拟结果和实测资料吻合较好,说明两个模型的建立是成功的.数学模型对深槽内水流的水力学性质研究表明,深坑处是深槽沿程受水流剪切力、冲击力以及弯道环流最大的区域.深坑被剥蚀和冲刷下来的泥沙通过弯道环流向对岸高滩输运,形成高滩不断淤高,深坑不断冲刷的状况.此外,由物理模型试验对深坑处流态的观察可知,深坑处于水流交汇和分汊不断变化区域,经常出现漩涡、汇流、紊流等不良流态,这些流态提高了水流紊动能量和挟沙能力,为深坑的发展提供了有利条件.三里埂汇流段水动力状况的数学模型和物理模型研究为该河段深坑的整治提供了理论依据.
