板桥峪抽水蓄能电站防沙措施的试验研究

Experimental Study on Sediment Preventing Measures for Banqiaoyu Pumped Storage Hydroplant

通过板桥峪抽水蓄能电站防沙问题的试验研究 ,阐述了解决此类电站泥沙问题所可能采取的措施 ,其中包括抬高水库水位运行 ,在拦河坝以上修建拦沙坝 ,增建拦沙潜坝和排沙洞等。并通过比尺模型试验对这些措施的防沙效果进行了比较和分析 。

Based on experimental results, this paper describes the possible measures for sediment prevention of Banqiaoyu pumped storage hydroplant. Comparisons and analyses have been made on the effects of the measures for sediment prevention, including raising normal water level in the reservoir ,building sediment control dam on the upstream of the dam, building submerged sediment control dam and sediment sluice outlet, etc. At last, a reasonable and feasible alternative measure has been suggested.
