摘　　要：为科学合理地确定孤山航电枢纽工程规模指标,需考虑下游已建丹江口水库的影响。通过分析丹江口水库水位变化规律,采用对比有、无丹江口水库影响的研究思路,分析了丹江口水库对孤山航电枢纽工程下游水位、水头、发电、出力、额定水头、下游最高通航水位等规模参数的影响。结果表明:丹江口水库水位越高,孤山航电枢纽与下游水位有关的工程规模参数选择受影响越大。考虑丹江口水库顶托影响确定的孤山航电枢纽工程规模参数更符合实际。In order to scientifically and reasonably determine project scale parameters of Gushan Navigation and Hydropower Project,it is necessary to consider the influence of Danjiangkou Reservoir which has been built downstream.By analyzing the variation law of water level of Danjiangkou Reservoir,the influence of the reservoir on scale parameters such as water level,water head,power generation,output,rated water head and the maximum navigable water level of the downstream of Gushan Navigation and Hydropower Project was analyzed by comparative study of two senarios with and without the reservoir.The results showed that the higher the water level of Danjiangkou Reservoir was,the greater the influence on the selection of project scale parameters related to the downstream water level of the project.The scale parameters of the project would be more reasonable by considering the influence of back water of Danjiangkou Reservoir.
