| 摘 要： | 以洮河峡城水电站为例,对西北地区多沙河流水电站防沙及冲沙效果进行了实体模型试验。结果表明:①站进水口前合理设置拦沙堰和导沙坎,泄洪冲沙闸进行敞泄拉沙的效果良好,拦沙堰前无大量泥沙淤积;②在电站引水口下方合理设置排沙道并择机排沙,在排沙道进口前能形成门前清,拉沙效果良好。同时,建议定期开启排沙道进行拉沙,确保排沙道畅通。

| Abstract: | Taking Xiacheng Hydropower Station in Taohe River as an example,we had done the sediment control and sediment eject effect of physical model experimental study of sediment-laden river in Northwest China.The results show that,a)in the power station entrance,setting up reasonable sediment detention weir and sediment guiding dike can play a role in promoting the sediment discharge,without a large sediment deposition before the sediment detention weir;b)under the power station water intake,setting up reasonable... |
