渔港新型开孔式水工结构消浪性能物理模型试验研究OA

To investigate the wave-dissipation performance of novel hydraulic structures in fishing ports under different wave conditions and to ensure safe berthing and operation of fishing vessels,this paper innovatively designs two new types of perforated hydraulic structures:non-connected holes and connected holes.Through physical model tests,the variation patterns of the reflection coefficients of these two new perforated hydraulic structures under different wave parameters are systematically analyzed to explore their wave-dissipation effects.The experimental results show that under composite wave conditions with large wave heights and long periods,the non-connected structure exhibits lower reflection coefficients compared to the connected-hole structure,indicating better wave-dissipation performance.In contrast,the connected structure demonstrates superior wave-dissipation effects under short-period waves and low-water-level conditions.This study can serve as a basis for structural selection in engineering design according to the characteristics of the design wave spectrum,providing important references for the optimized design of novel hydraulic structures such as breakwaters and wharves in fishing ports.
