黄河大河家至寺沟峡河段设计最低通航水位的推求

Calculation of design lowest navigation water level of river reach from Dahejia to Sigouxia river reach on Yellow River

黄河大河家—寺沟峡河段受在建的大河家水电站和已建的寺沟峡水电站综合调节作用,河段水文条件变化复杂,要对该河段进行经济合理的整治开发必须以确定合理的设计最低通航水位为保证。结合枢纽的运行特征,建立一维数学模型对本河段设计最低通航水位进行研究,从而得到合理的设计最低通航水位。

Influenced by both Dahejia hydropower and Sigouxia hydropower, Dahejia to Sigouxia river reach on the Yellow River is complex in natural condition, so it is necessary to assure the design lowest navigation water level in order to suitably and economically carry out the regulations and exploitation of this river. Considering the influences of Operating characteristics of two hydropowers, we establish one dimensional mathematical model to calculate the design lowest navigation water level, and obtain the reasonable design lowest navigable level.
