Interactions between multi-directional irregular waves and a pile group in a side-by-side arrangement: Probabilistic analysis
Abstract In a recent paper, Zhang et al. (2019) statistically analyzed the pile group effect of nine piles in a side-by-side arrangement exposed to multi-directional irregular waves. In this study, the corresponding data are further analyzed and their probabilistic distributions are examined. The Weibull distribution is used to fit the measured wave force, and the relationships between parameters A and B of the Weibull distribution are given, where it satisfactorily fitted the probability distribution of the measured wave force on the piles with the appropriate parameters. To explain the rules governing the probability distribution of the wave force, the relationships between this and the characteristics of force groupiness are studied. Variations in the parameters of the Weibull distribution and the average force coefficients are also examined using the proposed KC LD1/3 and relative spacing (S/D). The results show that the probability distribution of the irregular wave force on piles exposed to multi-directional irregular waves is strongly dependent on the wave directionality, KC LD1/3 numbers and relative spacing.
Highlights A probabilistic analysis of nine piles in a side-by-side arrangement exposed to multi-directional waves is carried out. Weibull distribution could adequately fit the probability distribution of the force on the piles. Probability distribution of wave force on piles are strongly dependent on the wave directionality.
