WAVE FORCES AND IMPACTS ON A CIRCULAR AND SQUARE CAISSON

J.W. van der Meer, E. Benassai

Abstract


The existing breakwater at Civitavecchia Harbour, Italy, will be extended with a part of caissons. In order to investigate wave forces for this caisson, the Ministero del Lavori Public! commissioned the Delft Hydraulics Laboratory to perform a model investigation on the proposed extension. In the first part of the study quasi-static wave forces on the entire caisson were measured by means of a force measuring frame. In the second part wave impacts were recorded by pressure cells at 22 positions of the caisson. The investigation contained two main items which are discussed in this paper: Comparison of quasi-static wave forces with maximum forces by wave impacts. Comparison of forces and impacts for a circular caisson with those measured for a square caisson.
