Abstract
This paper develops an integrated prevention and control technology of"advanced detection graded interception"to address the engineering challenges of the development of a rich water fracture zone and high risk of water and mud inrush in the tailwater tunnel of a hydropower station.By comprehensively utilizing geological radar,advanced drilling,and hydrological testing,precise detection of the location,scale,and permeability characteristics of water rich fractured zones can be achieved.Based on the classification of surrounding rock(Class Ⅲ-Ⅴ)and the risk level of water inflow(low,medium,high),establish a three-level interception system of"local grouting sealing curtain grouting anti-seepage combined reinforcement support".This technology can reduce the occurrence rate of water and mud inrush to 0,and the daily water inflow of the tunnel can be reduced from the predicted 80 m3/d to below 5 m3/d,significantly improving the stability of the surrounding rock.关键词
