摘要
通过对溪洛渡近3年的过机泥沙监测样本分析,主要包括泥沙含量、颗粒级配以及水温、p H值等物理化学指标,分析结果表明,泥沙含量与流量成正比;过机泥沙最大粒径基本都小于1 mm;硬颗粒主要为石英和长石,汛期占泥沙总量的约80%,易对水轮机产生磨蚀;水质监测结果表明过机水质良好,无腐蚀性。
The monitoring samples of sediment and water in Xiluodu Hydropower Plant in the last three years are analyzed, including the sediment content, particle grading, physical and chemical indexes such as the water temperature and PH value. The results show that the sediment content is proportional to the water flow rate. The maximum particle size passing through the turbines is basically smaller than 1 mm. The hard particles are mainly of quartz and feldspar, which are about 80% of the total sediment in flood season and may cause corrosion of the turbines. It also shows that the water quality is rather good with no corrosiveness.
