摘要
文章简述了天生桥一级水电站引水隧洞环锚预应力结构及环锚预应力施工情况,分析了环锚穿索张拉及充水发电前后的预应力结构变形和应力变化规律。表明在环锚预应力衬砌的压力隧洞中,主要荷载由预应力承担,但钢筋的作用及温度应力的影响是不可忽视的。
The paper briefly states circular anchor-prestress structures of diversion tunnel of Tianshengqiao Ⅰ Hydropower Station and its construction process,and analyzes deformation and stress variety behaviors of the structures before and after circular anchor cables are tensioned and tunnel is full with water for generation.This makes known that the main load is borne by prestress cables,but the action of steel bars and affect of temperature stress should not be ignored in a pressure tunnel with circular anchor prestress liners.
