摘要

为量化姜席堰河段水动力机制,结合步坑口水文站的水文资料与实际调查情况,运用现代水力学原理及数值模拟方法对姜席堰河段的水动力学机理进行推演,比较了上游不同来流量情况下,内外江的分流比、沿程流速、水位和流场变化,确定了姜席堰河段具体的分流机制以及可能产生冲刷与淤积的工程隐患点.基于模拟结果,推求了姜堰和席堰的流量系数,得出了姜堰与席堰的堰流公式,为姜席堰河段治理与防护提供了理论依据.

Abstract

To quantify the hydrodynamic mechanism of Jiangxiyan river section,this paper combined the hydrological data of Bukengkou Hydrological Station with the actual investigation to deduce the hydrodynamic mechanism of Jiangxiy-an by using modern hydraulics principles and numerical simulation.The changes of diversion ratio,flow velocity,water level and flow field of the inner and outer rivers under different inflow from upstream were compared.The specific diver-sion mechanism of the Jiangxiyan river section and the potential engineering hazards of scour and siltation were derived.The flow coefficients of Jiangyan and Xiyan were derived from the simulation results,and the weir flow equations of Jiangyan and Xiy-an were obtained.This study provides a theoretical basis for the management and protection of Jiangxiyan river section.
