拉浪水电站位于广西中部,龙江下游的岩溶地区。水库正常蓄水位177米,总库容1.02亿米~3,设计引水流量213.3米~3/秒。最大坝高38米,最大水头34米。总装机容量5.1万千瓦。厂房位于左岸坝线下游约72米。该电站于1966年施工,1971年开始蓄水发电运行,至今历时十多年,运行基本正常。但是左岸坝肩地形单薄,地下水位低于水库设计正常高水位23～31米,存在裂隙性渗漏,估算渗漏量为0.646米~3/秒。因施工时没有做好防渗处理,成为电站工程一大隐患。
Lalang Hydropower Station is located in central Guangxi, the lower reaches of the Longjiang karst area. The normal reservoir water level of 177 meters, the total storage capacity of 102 million meters ~ 3, the design diversion flow of 213.3 m ~ 3 / sec. The maximum dam height 38 meters, the maximum head 34 meters. The total installed capacity of 51,000 kilowatts. Plant located in the left bank dam line about 72 meters downstream. The power station construction in 1966, 1971 began water and electricity generation operation, which lasted more than 10 years, running basically normal. However, the topography of the left bank abutment is very thin and the groundwater level is below the normal high water level of 23 to 31 meters in the reservoir design. There is a fissure seepage and the leakage is estimated to be 0.646 m 3 / s. As a result of construction did not do a good anti-seepage treatment, a power plant project a hidden danger.
