BREAKWATER CONSTRUCTION METHOD
PROBLEM TO BE SOLVED: To provide a construction method for a breakwater having sufficient slide resistance against an assumed tsunami wave.SOLUTION: A value W2 necessary for making a slide resistance value R equal with assumed tsunami wave force P is derived, the slide resistance value being a sum of a slide resistance value R1 of a caisson 3 calculated by multiplying a weight value W1 of the caisson 3 by a frictional coefficient value μ1 between the caisson 3 and a mound 2, and a slide resistance value R2 obtained by multiplying a total weight value W2 of wave dissipating blocks 5 piled on an inner port side of the caisson 3 by a frictional coefficient value μ2 between a wave dissipating work 4 (a structure built by piling the wave dissipating blocks 5) and the mound 2. A breakwater 1 is constructed by piling the wave dissipating blocks 5 on the inner port side of the caisson 3, the wave dissipating blocks being of a quantity that makes the total weight greater than the value W2.SELECTED DRAWING: Figure 1
