长潭水电站位于我省蕉岭县石窟河长潭峡谷段内。水库集雨面积1990km~2。大坝坝型为混凝土重力坝,坝内式厂房。正常高水位148m的库容为1.145亿m~3。最大坝高73.9m。装机容量4×1.5=6万kW。本工程的兴建可获年发电量1.544亿kW·h,且可保下游六万亩农田在100年一遇洪水不成灾,以及扩大下游灌区面积15000亩。1978年3月动工,1986年8月大坝基本建成,将于近期蓄水发电。 本工程地质构造控制工程地质条件有一定程度的代表性。本文拟从地质构造块体的角度予以小结。
Changtan Hydropower Station is located in the province of Jiaoling County Grottoes River Canyon section. Reservoir rain catchment area of 1990km ~ 2. Dam dam type concrete gravity dam, dam-type plant. The normal high water level 148m storage capacity of 114.5 million m ~ 3. The maximum dam height 73.9m. Installed capacity of 4 × 1.5 = 60,000 kW. The construction of this project will generate 154.4 million kW · h of electricity per year and will ensure that 60,000 mu of farmland will be flooded in 100 years and that the area of downstream irrigation areas will be expanded to 15,000 mu. Starting in March 1978, the dam was basically completed in August 1986 and will generate electricity and water in the near future. The project geological structure control engineering geological conditions have a certain degree of representation. This article intends to summarize from the perspective of geological tectonic blocks.
