Abstract: (1459 Views)
Armors are a kind of protective layer made of stone or concrete, used in breakwater constructions or coastal lines, arrayed with specific regular or irregular pattern on the breakwater or the coast. Armor damage due to wave attack is the principal failure mode to be considered when designing conventional rubble mound breakwaters. Since the cost of breakwater construction is high, the stability of this structure during its service life is important. This study includes the results of a experimental study stability of rubble mound breakwater covered with armor layers consisting of parsian national armor. In these experiments using irregular wave, the effect of significant wave height, wave period and water level changes on the stability of these concrete armor parts. The results obtained from the damage of the armor layer in the form Nod are presented that the stability of the armor decreases with increasing values of significant wave height and wave period and the armor layer of the rubble mound breakwater will be damaged. The effects of progressive damage on other breakwater components against wave interaction were also evaluated and the results of this study show the efficiency of this New Recommended Concrete Armor.
