Abstract
The analysis of foundation piezometer records at main dam and saddle dam of Ramganga Project, has indicated that the single row grout curtain at main dam, is ineffective so far as the hydrostatic pressure reduction in foundation is concerned, whereas under similar conditions, upstream impervious blanket at saddle dam, is more effective in pressure reduction. Experimental test results by electrical analogy technique using graphite paper, has indicated that in case of Ramganga main dam, the total net pressure reduction for fully effective grout curtain would have been only 25%. The design curve for efficiency versus different openings in grout curtain is also given.

Efficacy of Grout Curtain at Ramganga Dam
The analysis of foundation piezometer records at main dam and saddle dam of Ramganga Project, has indicated that the single row grout curtain at main dam, is ineffective so far as the hydrostatic pressure reduction in foundation is concerned, whereas under similar conditions, upstream impervious blanket at saddle dam, is more effective in pressure reduction. Experimental test results by electrical analogy technique using graphite paper, has indicated that in case of Ramganga main dam, the total net pressure reduction for fully effective grout curtain would have been only 25%. The design curve for efficiency versus different openings in grout curtain is also given.
