Abstract

The use of traditional rubble-mound breakwaters to provide sheltered areas inside ports requires an enormous volume of fill material. Vertical structures are being used in Spain with greater frequency each day, because they reduce the use of rocks and rubble, materials which are becoming limited. This article describes two innovative solutions for the construction of breakwaters: driven caissons and bridge breakwaters formed by caissons. Two cases are shown at the Malaga and Ibiza ports where SENER and DRAGADOS suggested the use of these typologies. Both typologies involve important environmental benefits, since they eliminate or reduce drastically the dredging and the quarry materials necessary for the works. The geotechnical properties of each particular seafloo
