摘要
溪洛渡水电站位于金沙江下游,水流流速大,挟沙能力强,结合溪洛渡水电站导流洞推移质情况,开展了高速挟沙水流条件下卵石推移质测验方案的试验研究,提出了溪洛渡水电站卵石推移质测验方案即缆道悬挂采样器加拉偏的方式进行测量并予以实施。测验成果表明,金沙江溪洛渡6#导流洞河段存在河床卵石运动情况,而且推移量很大。根据导流洞实测水沙运动资料,揭示了溪洛渡水电站导流洞卵石推移质的输移特性,并建立了卵石推移质输沙率与流量的经验关系。
A feasible sampling method for gravel bed load transportation in diversion tunnel of Xiluodu hydropower station was carried out.The observation data showed the characteristics of bedload transport rate and discharge in diversion tunnel,and an empirical formula of bed load transport rate and discharge was obtained according to series of field data.
