某水电站大坝右岸灌浆平硐涌水处理施工技术

Water Surge Treatment Technology of Grouting Adit on Right Bank of a Hydropower Station Dam

针对某水电站大坝右岸灌浆平硐在水库蓄水后出现的涌水问题,笔者分析了涌水发生的原因,揭示了岩层发育特征对灌浆平硐涌水的影响,并提出了应急抢险处理的基本思路、应急处理施工方法以及后期工程处理的原则和方法。监测结果表明,处理措施得当,实施效果良好,可为类似工程、类似情况提供参考和借鉴。

In view of the water surge problem of grouting adit on the right bank of a hydropower station after reservoir impoundment,the author analyzes the causes of water surge,reveals the influence of rock stratum development characteristics on the water surge of grouting adit,and puts forward the basic ideas,construction methods of emergency treatment and the principles and methods of later engineering treatment.The monitoring results show that the treatment measures are appropriate and the implementation effect is good,which can provide reference and reference for similar projects and similar situations.
