碩士 / 立德大學 / 資源環境研究所 / 98 / Some marine structures have been reported to be damaged by seabed instability. Furthermore, it has been observed that a deep hole exists near the tip of a marine structure. It has been well documented that ocean waves propagating over the ocean surface exert dynamic pressure fluctuations on the sea floor. These fluctuations generate an excess pore pressure within the soil skeleton, which have been recognized as a dominant factor in analyzing the seabed instability. Numerous investigations for the wave- induced seabed response, including pore pressure, effective stresses and displacements, have been carried out since the 1970’s. However, all previous models have been limited to either one-dimensional or two-dimensional case, which can only represent part of the whole problem. Therefore, the three-dimensional model for linear wave-induced soil response in the vicinity of a breakwater will be established in this paper. Moreover, the influence of several wave and soil parameters on the wave-induced soil response and soil displacement was also discussed around breakwater heads.
