摘　　要：水库工程主要建筑物包括大坝(主坝、副坝)、溢洪道、输水洞等,其中副坝、溢洪道、输水洞均位于右岸。输水洞位于主坝右坝肩西140 m处,轴线总长385.13 m,采用岸塔式进水口,进口底高程为144 m,隧洞洞线纵坡为1%,闸孔尺寸为2.50 m×2.50 m(宽×高)。输水洞进出口开挖边坡和溢洪道两侧山体开挖边坡级别为3级。文章根据工程地质情况详细介绍了引渠段、控制段、洞身段、明埋钢管段及出口控制段、导流明渠等工程相关设计内容。The main structures of the reservoir project include dams(the main dam and auxiliary dam),spillway,and water conveyance tunnel,etc.,among which the auxiliary dam,spillway and water conveyance tunnel are all located on the right bank.The water conveyance tunnel is located 140 m west to the right abutment of the main dam,with a total axis length of 385.13 m,a shore tower intake with the bottom elevation of 144 m.The longitudinal gradient of the tunnel is 1%,and the gate hole size is 2.50 m ×2.50 m(width × height).The excavation slope at the entrance and exit of the tunnel and the mountain excavation slope on both sides of the spillway are of level 3.In the paper,based on the engineering geologic conditions,the approach channel section,the control section,the tunnel section,the open buried steel pipe section,the exit control section and the open diversion channel are introduced in detail.
