李家沙特大桥防洪评价数值模拟分析

Numerical Simulation Analysis of Flood Prevention Assessment on Lijiasha Bridge

根据相关法律法规,涉河建筑物需开展防洪影响评价工作,水文分析计算为防洪评价工作的主要内容。目前,一、二维水动力数学模型联合运用在防洪评价数值模拟计算中较为常用。以李家沙特大桥为例,阐述了防洪评价模拟计算中一、二维水动力数学模型的应用情况。

According to relevant laws and regulations,it is required to carry out flood prevention assessment on construction projects built inside the river channel.Hydrological analysis and calculation is the main content of flood prevention assessment.At present,one-dimensional and two-dimensional hydrodynamic model are usually used in the numerical simulation.In this paper,numerical simulation analysis is described.
