摘 要:双联拱隧道因跨度大,结构复杂,从受力角度分析存在很多不利因素,尤其是中隔墙部位拉、压、弯、扭、剪均有,受力十分复杂。另外,中隔墙顶部防水也是一个施工重点和难点。因此,中隔墙的施工更是双联拱隧道施工的关键。

Abstract: For the large span and complicated structures, the highway wall-arcade tunnels have many disadvantageous factors from the aspect of force analysis. In particular, the top of the middle-wall receives pull, stress, turn and cut, so the force received by middle-wall is very complex. On the side, the water-repellent step for the top of the middle-wall is also a keystone and a difficulty in construction.
Key words: wall-arcade; tunnel; middle-wall working; water-repellent step
