摘　　要：为减少泥沙淤积对库容的影响,古城水电站采用了"正向泄洪冲淤,侧向取水"的布置型式。在首部枢纽闸坝设置了2孔泄洪拉沙闸,进水口前缘设高2.0m的拦沙坎,坎内进水口前布置生态输水管进口,通过生态输水管将进水口前的沉积物排至下游。组成泥沙"拦、排"系统,有效地解决了推移质泥沙进入取水口问题。In order to reduce the influence of the sediment on in Gucheng Hydropower Station, which could be described as the reservoir storage ＂flood discharging capacity, a specific layout is adopted and sediment flushing in front direc- tion, and water intaking in lateral direction＂. Two flood discharging and sediment flushing gates are arranged in the head dam. While, a two-meter high sediment barrier is set on the intake front edge. Entrance of an ecological water di- version pipe is then set after the sediment barrier and before the water intake. Thus, the sediment before the water in- take could be flushed downstream through the ecological water diversion pipe. With this sediment barrier and flushing system, the sedimentation problem in the water intake is effectively resolved.
