天桥水电站日运行方式对航运影响的初步研究

Preliminary Research on the Navigational Condition Influenced by Tian Qiao Hydroelectric Station During Daily Regulation

本文以黄河天桥水电站为计算实例,应用北干流14个水文(位)站的历年实测资料、典型年的逐时(分)实测资料,在统计、分析处理大量数据的基础上,比较准确地定量分析了天桥水电站调峰对下游府禹段航运产生的不利影响。

Taking Tian Qiao hydroelectric station (on Yellow River) as an example this paper introduces the past yearly observed data of 14 hydrographic stations that situated in the north main stream, and the observed real time (in minute) data in a typical year.On the basis of statistics, analysis and treatment for a large number of existent data,the authors provide a quantative analysis of the worst condition to the situation of water transportation within Fu Yu downsteam reach when Tian Qiao hydroelectric station is under operation with daily regulation fo peak load.
