摘要
对于水电工程中引水隧洞出现的重大突涌水灾害通常只能被动防治,其主要原因在于人们对突涌水发生的机理认识不够深入,缺乏有效指导引水隧洞突涌水灾害的预测预警和防治的系统理论与方法。而针对引水隧洞突涌水制定的处理措施中的每一个细节和步骤都是至关重要的,将直接影响到后期的施工质量。引水隧洞的突涌水处理应符合“预防为主、疏堵结合”的原则,即采取突涌水疏通、引排结合、注浆封堵的方式。阐述了引水隧洞突涌水条件下的注浆堵水技术,提出了有针对性的措施并予以实施,取得了较好的效果。
For a long time,the major water inrush disasters in diversion tunnels have been in the passive prevention and control situation,the main reason is that people do not have a deep understanding of the mechanism of water inrush,there is no effective system theory and method to guide the prediction,Early Warning and prevention of water inrush disaster in diversion tunnel.Every detail and step of water gushing treatment measures of diversion tunnel is very important,which will directly affect the later construction quality.The treatment of water gushing in diversion tunnel should accord with the principle of“Prevention first,combining drainage with grouting and plugging”,that is,the way of water gushing and draining combined with grouting and plugging.Therefore,this paper tries to carry on some discussions to the water-blocking work of the water diversion tunnel project,and puts forward the pertinent measures.
