中文摘要 | 湖山水庫為離槽水庫,於清水溪流域建置桶頭攔河堰越域引水以為挹注,因規劃堰址處河 床屬軟弱岩盤,且近年沖刷嚴重,攔河堰設計與施工最大挑戰為克服高流速高沖刷課題,經評 估後採用直落式自由溢流堰型式,於堰址處配置消能池方式,依據水理分析可能沖刷影響範圍 及深度,於消能池四周以基樁基礎形式,確保消能過程設施安全,導引高沖刷水流能量於此處 安全消減。 |
英文摘要 | Hushan Reservoir is an off-site reservoir which diverting water from Tongtou weir on Chingshui watershed. Due to the nature of soft bedrock and the problem of erosion on the weir site, the most difficult challenge for the designing and construction process is to resolve the high-speed water erosion problem. After the assessment through hydraulic analysis, the area and depth affected by erosion were determined. As a result, a free weir, a stilling pool and piles were designed to mitigate the influence of erosion. |
