摘要/Abstract

摘要： 三峡大坝175 m成库运行后将对变动回水区的水流特性产生重大影响,对其展开分析将为该河段的航道整治、通航规划、水沙规律研究提供重要理论支持。在长江上游水文局实测资料基础上,选择变动回水区中段猪儿碛河段作为典型代表河段,采用数值模拟与原形观测数据理论分析相结合的方法,借助Aquaveo.SMS软件建立平面水流二维数学模型,将年内各时段与有无回水影响的各种工况进行组合,分析探讨了回水作用对流场、流速横向分布、水动力轴线等水动力条件的影响。分析成果可为该河段的河流研究与航道治理提供依据,建立的数值模拟方法可为同类河段的数模研究提供参考。

关键词: 三峡大坝猪儿碛河段, 175 m蓄水, 水流特性, 平面水流二维数学模型, 水动力条件

Abstract: The operation of Three Gorges Reservoir at 175m impounded water level will have a significant impact on the flow characteristics in backwater area. Analysis in this regard will provide theoretical support for the waterway regulation, navigation planning, and study on water and sediment regularities. According to the observed data from hydrology bureau in the upstream of Yangtze river, we employed Aquaveo.SMS to establish a two-dimensional plane flow model, and simulated the hydrodynamic conditions in the presence of and in the absence of backwater in different periods of year to analyse the influence of backwater on hydrodynamic conditions (flow field, horizontal distribution of flow velocity, and hydrodynamic axis). Zhuerqi reach in the backwater area is selected as a typical example for the research. The numerical simulation method could be taken as reference for similar study.

Key words: Zhuerqi reach, 175 m impoundment, flow characteristics, 2D mathematical model of flow, hydrodynamic conditions
