摘　　要：为合理设计旭龙水电站引水隧洞布置线路与结构,根据工程总体枢纽布置,结合地形地质条件,开展了隧洞线路布置和洞径比选工作。通过计算引水隧洞结构内力,设计进口渐变段、洞身段与钢衬段结构,确定了合适的立面型式及隧洞洞径,优化了引水发电系统流道布置,避免了上游调压室的设置。运用弹性力学有限元法,计算了引水隧洞不同工况下的整体稳定性。结果表明:旭龙水电站引水隧洞洞室满足稳定性要求,研究成果可为类似引水发电流道设计提供参考。In order to reasonably design the route and structure of the headrace tunnel of Xulong Hydropower Station,based on the overall layout of the project and the topographic and geological conditions,through calculating internal force of the headrace tunnel structure and design of transition section at the entrance,tunnel body and steel lining section,the tunnel route layout and tunnel diameter comparison were carried out,the appropriate elevation type and tunnel diameter were determined,the flow path layout of the diversion and power generation system was optimized,and the setting of the upstream surge chamber was avoided.The stability of the headrace tunnel under different cases was carried out by using elastic FEM.The results showed that the headrace tunnel chamber of Xulong Hydropower Station can meet the stability requirements.
