In the case of temporary road construction along the coast, cases of protecting offshore slopes by laminating bags filled with crushed stones are increasing. The method of packing cobblestones in a bag is a material in which a filling material is packed in a synthetic fiber net. This construction method has the advantage of being able to perform rapid construction. In addition, the authors have developed a highly constrained bag that can be expected to have higher stability against waves than conventional ones. In this study, the wave resistance stability of a temporary road slope covered with the highly constructed bag is investigated.
Experiments on the cross section of the dike confirmed KD values of 12 to 13 and wave reflectance KR of 0.25 to 0.45. In addition, it was confirmed that the high-restriction type bag exhibits higher stability against waves than the conventional type. Wave height is the only parameter in calculating the KD value. However, in this study, it was suggested that there was a difference in stability depending on the period. Therefore, as a result of evaluating the irregular wave energy and damage rate, a good relationship was obtained.
