SSC SSC JE Civil 2025 Mock Test Series (Paper 1 & Paper 2) Irrigation Engineering Dams and Spillways
Consider the elementary profile of a gravity dam with no tailwater and 55 m upstream water depth at full reservoir conditions. Suppose the limiting base width of elementary profile required for no tension development with full uplift is B1 and the limiting base width of elementary profile required to be safe in sliding with no uplift is B2. Then which of the following is correct? Take specific gravity of dam material is 2.4 and the coefficient of friction 0.65.
1
B1 = 46.5 m and B2 = 54.6 m
2
B1 = 35.5 m and B2 = 35.3 m
3
B1 = 46.5 m and B2 = 35.3 m
4
B1 = 35.5 m and B2 = 60.5 m
