Determination of wave loads on sloping structures

Selivanov, L. V.

Conclusions 1. The maximum value of the wave pressure from wind waves on slopes m=3.5 are up to 30% greater than the normative design pressure. 2. The diagram for the impact wave pressure on the slope has the form of an isosceles triangle. The pressure is distributed on the slope at a distance equal to one half the wave height. The maximum wave pressure diagram, constructed according to the recommedations given in the norms, is very long. 3. With mean wave heights of 0.40–0.85 m, the duration of the wave impact is 0.002–0.05 sec. 4. The probability of occurrence of a maximum wave pressure corresponding to impact of a wave having maximum dimensions upon an uncovered slope is equal to the product of the probabilities of occurrence of a wave having maximum dimensions and absence of a water base in the ebb from the preceding wave at the place of impingement of the wave. For slopes m=3.5, the probability of occurence of the condition of exposure of the slope below one half the maximum wave height does not exceed 0.01. The results of the investigation may be used for introducing corrections in the analysis of the wave pressure on slopes. To establish more accurately the wave pressure characteristics for large wave heights, it is necessary to carry out additional full-scale measurements under suitable conditions.
