摘要
对嘉陵江下游受电站下泄非恒定流影响严重的河段的设计最低通航水位进行研究。在深入分析嘉陵江桐子壕电站2009—2010年大坝下游水位、出库流量和电站调度运行方式的基础上,采用不同时间尺度的流量资料推求电站下游航道设计最低通航流量,通过建立滩险处基本水尺与电站坝下水位相关线来推求整治滩险的设计最低通航水位。
The design lowest navigable stage of Jialing river downstream waterway affected by unsteady flow of hydropower station is researched. Based on the analysis of the downstream water stage of hydropower station, storage outflow in the period of 2009--2010 and hydropower station operation mode in the Jialing river, we calculate the design lowest navigable discharge of downstream waterway of hydropower station using storage outflow in different time scales, and calculate the design lowest navigable stage of downstream waterway of hydropower station by water stage linear correlation between water gauges.
