导流洞

作为新增项目，1B标承担了导流洞封堵的改建和封堵工作。

As additional project , 1B Lot includes reconstruction and plugging of diversion tunnel .

边坡最大组合坡高达420m，上游与倾倒蠕变岩体自然边坡连成一体，坡脚布置有9条大直径引水隧洞，其下与导流洞进口开挖区连成一片，形成轮廓复杂的高边坡。

Nine big excavation water-intaking tunnels lie at its foot . It is interconnected with excavated slope of the diversion tunnel 's intake , forming a high slope with complex outline .

本研究以一个具体水电站的导流洞为参考，建立其隧洞的几何模型，并应用ANSYS软件对其开挖过程进行了数值模拟，通过不同工况下的计算结果对大型隧洞开挖方法进行了分析。

The geometrical models of the tunnel are established . And the ANSYS software is employed to simulate the excavation process . The excavation methods of large-scale tunnels are analyzed according to the calculation results under different operating conditions .
