Abstract: Based on data of drainage, sediment content, seepage, underground water level and leakage on slope, combined with the forecast results by seepage BP network model, the paper analyzed the effect of drainage hole grouting and slope filtration drainage protection of Yele dam. The analysis showed that: (1)soon after treatment, abnormally increase and decrease of drainage and turbid were found with some drainage holes. Local groundwater level changed greatly, which became stable later; (2) total seepage flow was decreasing and tended to be stable, but the seepage flow had the trend to transfer to river bed; (3) the leakage from side slope decreased. The analysis result proved the effectiveness of treatment by drainage hole grouting and slope filtration drainage protection. At the same time, some suggestions were advanced on monitoring, computation and treatment in the future.
