| 概 述 |
| 海尔霍尔坝位于加利福尼亚州鲁比肯（Rubicon）河上，距萨克拉门托市129km，是普莱瑟县中福克工程系统中的一项关键工程。坝基为辉长岩，坝址控制流域面积295km2，多年平均径流量4亿m3，有记录的洪峰流量188m3/s，总库容3亿m3，有效库容2亿m3，水库面积5km2。斜心墙堆石坝，最大坝高125m，坝顶长472m，坝轴线呈弧线形，曲率半径为1219m。上游坡为1∶2.5，下游坡为1∶1.4，上游坝面作成6m高的多级台阶。心墙上游坡为1∶1.57，下游坡为1∶1.34。无控制溢洪道溢顶为上溢式混凝土堰，最大泄量1960m3/s。利用导流隧洞改建成发电引水管和放水管。厂房布置在左岸岸边，装机容量725kW。工程于1966年完工，电站于1984年建成，后来将引水管道延长至下游17km的新电站，装机容量10.98万kW。 |
