| The profound study of wave propagation, characteristics of flow field and interactions between wave and sea road in shallow water is very important to the theoretical research and practice. The dissertation reviews the development of research, carry out the finite element analysis and numerical simulation of interaction between waves and sea roads.Based on the fluid-structure coupling function of the ADINA software, this thesis has taken a finite element analysis of three different types of sea road structures, including the whole slope sea road, the big stone armor sea road, and the small stones armor sea road, under the effect of the wave. Then it carries a qualitative analysis of these types of sea roads separately from the results of displacement, stress, strain, wave forces, which is based on wave horizontal force and wave uplift force acting on the measured points arrangement on the structure.This thesis study indicates that the whole slope sea road has taken a relatively minimal stress for it acts as a whole structure under the effect of wave. On the other hand small stones armor sea road has taken a largest stress, and slope foot armor stone is easy to be instable and failure. So it proposes to pave more stones at the bottom of sea road for protection in engineering design.Adding relative single slope shoulder compound section of section stress is small, but is prone to stress concentration at shoulder Ahgle machine, can be protection by laying large stones. According to the compound section topography result it suggests a reasonable choice in engineering design.As this paper has simplified the boundary conditions of interaction analysis between wave and sea road without fully considering the effect of underwater foundation, that interaction among the underwater foundation-sea road-wave remains to be further studied. Meanwhile study for best shouldered compound section position also needs further research. |
