A Novel Solution Structure to Decrease Elevation of Sea Dike Crest
Nowadays, there are two main types of sea dike: sloping dikes working based on pile foundation principle and vertical wall-typed dikes working based on gravity principle. Vertical wall-typed dikes are not widely used because of their complicated structure, construction and high cost. Sloping dikes were applied more widely than vertical wall-typed dikes because of their simple structure, construction and low cost. However, the cross-section of a sloping dike lets the wave run-up on the slope. Therefore, the wave run-up height has been higher than the wave height in front of the structure. It leads to an increase of thecrest level of sea dike. In many cases of designing, the wave overtopping was accepted to decrease construction cost. In this paper, the authors have applied a new structure: hollow structure (KCR), which works on both gravity principle and pile foundation principle by KCR sidestep shape dike. Authors also have used ANSYS software to simulate interaction of wave run-up and three sea dike structures: Tien Lang sea dike, outer revetment of Lach Huyen port and sloping dikes in the same environmental condition. Results have proved that the wave run-up height has decreased from 43.96 to 77.76%, crest level of the dike has decreased from 1.01 to 5.07 m, respecially, a construction cost has reduced to 40–70%. Those results have indicated that KCR will be ahigher quality and effective investment of sea dike.
