摘要 大朝山水电站总装机容量1350MW,总库容9.4亿m3,多年平均发电量59.31亿kW·h。电站总体设计的特点有:采用河床式碾压混凝土溢流重力坝,右岸地下厂房,长尾水隧洞的总体布置;枯水期基坑施工导流方案;利用当地凝灰岩和磷矿碴混磨作为混凝土掺合料;利用洞挖石碴作人工砂石骨料原材料;大跨度地下厂房洞室群和阻抗式尾水调压井;机组进水口前双向冲沙廊道等。在施工中还进行了一些设计优化,对实现总进度和投资控制目标起了重要作用。 Dachaoshan Hydropower Station has the total installed capacity of 1350 MW, the total reservoir storage of 940 million m 3 and the mean annual power output of 5.931 billion kWh. The characteristics of the overall design of the Station are as follows: RCC overflow gravity dam in river channel, the layout of underground power house and long tailwater tunnel in the right bank, the foundation pit construction diversion, using the mixture of local tuff and phosphorous slag as raw material of artificial aggregate, large span chamber group for underground power house, reluctance type tailwater surge shaft, double direction sand flushing gallery before intake. In the construction, the optimal design has been conducted, which plays an important role in the accomplishment of the general schedule and the investment control goal.
