Profile of high masonry gravity dam

PROFILE OF HIGH MASONRY GRAVITY DAM Mr. G. Molesworth gave the following formulae for fixing. These formulae are applicable for masonry gravity dams only. \[x= \sqrt{\frac{1.76y^{3}}{p_{a+1.06y}}}\] But value of x should not exceed y ρ at any cost \[Z= \frac{y}{36.5p_{a}}\] where x = D/S offset from the vertical line also known as axis of the dam at a depth y below the maximum reservoir level. Z = U/S offset from the vertical line at a depth y metres. b1 = Base width of the dam at 4 h below the full reservoir level. a = Thickness of the dam at the full reservoir level. It is taken as 0.4 b1. pa = Allowable compressive stress for masonry in t/m2, the value of which may vary between 77 to 110 t/m2.
