| description | The effects of submerged berms in attenuating the momentary liquefaction beneath rubble mound breakwaters under regular waves were investigated in a recent study. The present work aims to investigate the momentary liquefaction probabilities around and beneath breakwaters with submerged berms under random waves. The interaction between waves and breakwaters with submerged berms has been simulated through a phase-resolving numerical model. The soil response to the seabed pressure induced by random waves has been investigated using a poro-elastic soil solver. For three different breakwater configurations, the liquefaction depths under random wave conditions have been compared with those cases under representative regular waves. In the present study, the offshore spectral wave height (<inline-formula> <math display="inline"> <semantics> <msub> <mi>H</mi> <mrow> <mi>m</mi> <mn>0</mn> </mrow> </msub> </semantics> </math> </inline-formula>) and the peak period (<inline-formula> <math display="inline"> <semantics> <msub> <mi>T</mi> <mi>p</mi> </msub> </semantics> </math> </inline-formula>) of irregular waves are used as representative regular wave parameters. Results reveal the importance of considering random waves for a safe estimation of the momentary liquefaction probability. Indication about the minimum number of random waves, which is required to properly catch the liquefaction occurrences, has been also addressed. |
