NEW CONFIRMATION OF THE FORMULA FOR THE CALCULATION OF ROCK FILL DIKES

Ramon Iribarren, Casto Nogales

Abstract


In the paper entitled "Una formula para el caloulo de los diques de escollera" (A Formula for the Calculation of Rock Fill Dikes) published July 1938* there was presented the expression,
P=NA^3d/((cosa- sina)^3(d-1)^3)
where
P = weight of the individual stones or blocks in kilograms
N = 15 for dikes of natural rook fill
N = 19 for dikes of artificial block fill
A = 2h = total height of the wave that breaks on the dike,measured in meters
d = specific weight of material of the stones in tons (metric) per oubic meter
a = angle of the dike's side slope with the horizontal

Keywords


armor stone sizing; breakwater design; groin design
