Abstract：The South to North Water Diversion East Canal Project in Beijing is a strategic foundation project to ensure water supply security in the southeastern region of Beijing.Based on the summary and statistics of cracks observed in the tunnel body after emptying,the causes and hazards of cracks were analyzed in this study.The engineering treatment measures for sealing small cracks in long-distance water transmission tunnels using water-based inorganic permeable crystalline materials were proposed,and the effectiveness of crack anti-seepage and reinforcement treatment were evaluated.The research results indicated that applying water-based inorganic permeable crystalline materials could improve the compressive strength of concrete and repair fine seepage channels,which had certain reference significance for similar engineering anti-seepage reinforcement.
