港池边坡开挖对护岸工程的影响研究

摘要

影响设计波浪的因素,除了港区波浪条件、掩护状况以外,还包括平面布置和地形条件等.当护岸前需开挖形成港池,开挖后水深明显加大,港池开挖边坡的存在改变了波浪的传播方向,会对护岸上水范围和越浪量等产生重要影响.本文以某码头工程为例,通过波浪物理模型试验,从护岸上水范围、加高措施和越浪量三个方面,研究了港池边坡开挖对护岸的影响,供设计人员在进行类似工程设计时参考.%The facts that influence the design wave include not only the wave conditions and sheltered situation of a harbor, but also the plan layout of this harbor and local terrain conditions. The water depth increases significantly after harbor basin is dredged in front of revetment, the presence of the excavated slope changes the wave spreading direction, and influences the range and volume of wave overtopping the revetment greatly. Based on a terminal project, the influence of harbor basin slope excavation on the revetment is analyzed from the aspects of wave overtopping range, heightening measures and overtopping volume by adopting physical model test of wave. The research results will serve as a reference for the design similar projects.
