中文摘要:
      针对受离岸高桩码头掩护的后方护岸工程设计波浪难以确定的问题,结合实际工程,通过波浪断面物理模型和局部整体物理模型试验,研究码头工程对护岸设计波浪、越浪量和断面结构稳定性的影响。结果表明,高桩码头上部结构对后方护岸有良好的掩护效果,尤其在高水位时,消浪效果较好;受掩护良好的后方护岸工程,堤顶高程受高水位控制,可以适当降低堤顶高程;护岸结构稳定性,尤其护底、护脚块石,主要受较低水位控制,而低水位时码头对护岸的掩护效果有限,波高降低幅度很小。
英文摘要:
      Aiming at the problem that it is difficult to determine the design wave data of the rear revetment works sheltered by the offshore high-piled wharf,this paper combines the actual project with the 2D wave physical model and 3D wave physical model tests,and studies the design wave,overtopping and cross-section stability of the revetment under the influence of the wharf. The results show that the superstructure of a high-piled wharf has a good shelter effect on the rear revetment works,especially at the high water level has a good effect on wave attenuation. The embankment top elevation of the rear sheltered revetment is controlled by the high water level,and the embankment top elevation can be appropriately reduced. The stability of the revetment structure,especially the bottom protection and foot protection,is mainly controlled by the lower water level,but wave height reduction is limited because of the bad sheltered by the wharf when the lower water level.
