Sažetak
The calculation of the minimum required widths of a concrete vertical wall breakwater with respect to the stability criteria of overturning, sliding and settling is presented in die paper. It is assumed that the vertical wall breakwater is built on a foundation and located in the conditions for non-overtopping and overtopping by incident waves. In the analysis of wave forces on the vertical wall breakwater a distinction is made between the action of nonbreaking, breaking and broken waves. The disturbing nonbreaking wave forces are calculated using Sainflou's and Molitor's methods. The breaking wave forces are calculated according to the method developed by Minikin, and the broken wave forces according to the method proposed by the CERC (Coastal Engineering Research Center). Using the derived expressions and appropriate values of the safety factor for overturning and sliding, and allowable normal stress of the foundation for settling, and applying the assumed environmental conditions, it is possible to determine directly the minimum required width of a vertical wall breakwater. A numerical example in which the minimum required widths of a vertical wall breakwater in different wave load conditions are calculated according to the analyzed stability criteria is also given in the paper.
