港池开挖对护岸工程影响试验研究

Test research on impact of excavation of harbor basin on revetment

通过物理模型试验,研究港池开挖前后波高分布变化及对护岸工程的影响。结果表明,港池开挖对护岸前设计波浪要素影响很小,对扭王字护面块体稳定、防浪胸墙稳定、越浪量和堤后冲刷影响也较小,对护底块石稳定有一定影响,但不是引起护岸破坏的原因。

Based on the physical model test, the article discusses the wave height distribution before and after the excavation of harbor basin and the impact of the excavation of harbor basin on revetment engineering. Results show that the impact of the excavation of harbor basin on design wave elements in front of revetment is very small, and that on the stability of accropodes and crown wail, wave overtopping and the scouring behind the dike is also small. The excavation of harbor basin has some impact on the bottom protection stone block, but not the cause resulting in the destruction of revetment.
