长大隧道施工中地下水处理

Treatment of groundwater in construction of Changdai Tunnel

介绍了几种地下水的探测和预报方法,针对施工中可能突发漏水的部位,依照“以堵为主,堵排结合”的处理原则,提出了地下水的处理方法,有效地防止了地下水对施工的危害,确保了长大隧道的施工质量。

Several detection and prediction methods of groundwater are introduced. According to the vulnerable water flush parts in construction corresponding groundwater treatment methods are proposed according to the principle 'based upon blocking up and combined with drainage' to prevent the damage of groundwater to ensure the construction quality of Changda tunnel.
