Application of Inclined-holes Curtain Grouting in the Seepage Control of the Reservoir

Based on the analysis ofthe leakage after two impermeable treatments of Suyoukou reservoir in Su'nan County,Gansu Province,the vertical curtain grouting program was proved to fail to prevent leakage.In this study,the inclined-holes curtain grouting program was recommended.This program could significantly reduce the reservoir leakage and fulfill the desired objective.At the same time,it provided a new way and accumulated some experience for the inclined-holes curtain grouting technology at the foundation and abutment of the dangerous dam.

Key words:Suyoukou reservoir,inclined-holes curtain grouting,dangerous reservoirs,anti-seepage treatment
