摘要
通过水工模型试验,对赣江石虎塘航电枢纽[1]的电站取水口局部区域的水力、泥沙运动规律进行了研究,在确保电站无论在正常蓄水位情况还是在全闸敞泄情况下,电站均能够引用到足够的水量用以发电,在研究电站取水口原布置方案的基础上,对其布置形式进行了优化。试验表明,模型所提出的优化布置形式能够最大限度地满足电站取水发电要求,水流条件也平稳顺畅,避免了取水口处泥沙淤积而导致引水不畅问题,有利于电站取水口的安全、可靠运行,符合实际要求。
Through hydraulic model test, the paper studies water and sediment movement at some part of water intake of power station at Shihutang Navigation-power Junction built on the Ganjiang River in order to ensure that the power station has sufficient water to generate electricity under normal pool level or water release with the gate fully opened. The arrangement of the water intake is optimized on the basis of its original layout. The test shows that the proposed model of the optimized layout enables the power station to generate electricity to the greatest extent. Such layout provides favorable water conditions at the water intake where diversion works smoothly without sediment deposition so that the intake can work safely and reliably.
