ABSTRACT
Mengjiagou reservoir is located in Mengjiagou village, Baicheng town, Gaomi city, upstream of the main stream of Jiaohe river. The loose layer of reservoir dam foundation is mainly sandy soil with large permeability coefficient, which belongs to strong permeable or extremely strong permeable layer. If anti-seepage measures are not taken, the reservoir water will leak seriously through the loose layer of dam foundation. This paper analyzes the leakage of the dam foundation without seepage interception measures, and through scheme comparison, selects the anti-seepage design scheme of adopting plastic concrete seepage interception wall in the dam section downstream of the sand consolidation dam and concrete seepage interception groove in the dam section upstream of the sand consolidation dam, so as to ensure the normal exertion of engineering benefits.
