老挝南塔河1号水电站发电引水系统布置

Layout of Power Generation and Diversion System of Nam Tha No.1 Hydropower Station

结合工程地形地质条件,介绍了老挝南塔河1号水电站发电引水系统的布置原则及具体建筑物布置,隧洞在地质条件差、大直径、高水头的条件下采取一系列的工程措施加固设计,电站蓄水运行后通过放空检查,隧洞内渗漏、变形、应力等观测数据均在正常范围内,沿线山体也没发现渗水现象,证明发电引水建筑物布置合理。

Combined with topographic and geological conditions of the project, this paper introduces the layout principle and specific building layout of the power generation and diversion system of Nam Tha No.1 Hydropower Station in Laos. Under the conditions of poor geological conditions, large diameter and high water head, a series of engineering measures are taken to reinforce the tunnel. After water storage operation of the power station, through the emptying inspection, the observation data of leakage, deformation and stress in the tunnel are all within the normal range, and no water seepage is found in the mountains along the line, which proves that the layout of the power generation and diversion structure is reasonable.
