Abstract

Abstract: To reflect the channel characteristics of Chongqing urban reach of the Yangtze River and to determine the discharge of forming the river bed, the dominant discharge was calculated by Makovieve method and frequency analysis method, which was based on the measured data of the Yangtze River committee hydrographic office from 1961 to 2007. Through the comprehensive analysis on the calculation results of the above two method, the bed-building discharge of Cuntan reach and Xuantanmiao reach was recommended. Finally, the empirical formula between the bed-building discharge and the hydraulic parameters was established through the multiple regression analysis, and its results could offer the reference for the channel governance of reaches and the determination of the dominant discharge of the reaches with the same kind.

Key words: waterway engineering, dominant discharge, frequency analysis

摘要： 为反映长江干流重庆主城河段河道特性，确定出造床流量，根据长江上游水文局1961-2007年的实测资料，利用马卡维耶夫法和频率分析法分别对造床流量进行了计算，通过对二者方法及计算结果的综合分析，推荐了寸滩河段及玄坛庙河段的造床流量值。通过多元回归分析，建立了造床流量与水力参数的经验公式，其结果可为各河段的航道治理以及同类型河段造床流量的确定提供参考。
