4.2.6 Gravity (concrete) dam analysis, stability (overturning, sliding), stress and material failure
Examine the stability of the gravity dam shown in figure below considering seismic effects. Also indicate the values of various kinds of stresses that are developed at heel and toe. Uplift may taken same as hydrostatic pressure at base of corresponding faces and is considered to act over 60% of the base area. Seismic coefficients (α) are 0.1 and 0.05 for horizontal and vertical directions respectively. Take, γc=24 KN/m³ and γw=10 KN/m³. [10]
