Indian standard (IS) for Design of Dam

Indian standard (IS) for Design of Dam

1. Criteria for Design of Solid Gravity Dams- I.S. 6512-1984.
2. Guidelines for fixing spillway capacity –I.S. 11223-1985.
3. Criteria for Earthquake resistant design of structures I.S. 1893-1984.
4. Code of practice for stability analysis for earth dams- I.S. 7894-1975.

The Indian Standard IS: 11223-1985 “ Guidelines for fixing spillway capacity” gives the criteria for inflow design flood as under:
The seismic zone together with appropriate coefficients for use in such analysis is given in IS: 1983-84 “Criteria for Earthquake Resistant Design of Structures”.

The various design condition of analysis along with the minimum values of factors of safety to be aimed at and use of type of shear strength for each condition of analysis is given in I.S.:7894-1975 Code of Practice for stability analysis of earth dams .
IS:1893-1984. Criteria for earthquake resistant design of structures (3rd rev.).
Till specific reliable procedures become available for assessment of ice pressure, it may be provided for at the rate of 250 kpa applied to the face of the dam (I.S..6512-1984).
I.S. 1893-1984 “Criteria for Earthquake resistant design of structures” or similar Method.
As per Indian Standard IS:6512-1984 the compressive strength of concrete and masonry
The IS : 6512-1984 states that the factor of safety against sliding may be calculated on the basis of partial factor of safety in respect of friction (FQ) and partial factor of safety in respect of cohesion (Fc)
