Abstract
The scheme of excavation and backfill of clay is adopted for seepage control treatment of the dam foundation.The heavy silty loam,pebbles and fully weathered dolomite quartz schist will be removed from the dam foundation and the impermeable soil will be used for backfill.Based on the the specific conditions of the project,the curtain grouting construction and sandbag for reverse filter will be adopted.The width of cutoff trench is 13m.The curtain grouting will be adopted for seepage control of the dam foundation and the curtain axis is located 2.40 m upstream of the dam axis.The top of the curtain is the bottom of the impermeable body.On the top of the curtain is concrete plate of 10m long and 0.60m thick as the grouting platform.Based on the analysis of the geology,geomorphology,strata and permeability coefficient of the reservoir dam area,the scheme of excavation and backfill of clay is adopted for the anti-seepage treatment of the main and auxiliary dam foundations.Through the comparison of dam foundation anti-seepage treatment alternatives,the vertical seepage prevention measures for seepage control of the reservoir dam foundation is described in detail.关键词
