斜坡式海堤挡浪墙稳定性试验研究

通过模型试验验证了波浪作用下斜坡式海堤各设计方案的挡浪墙及其它各部位的稳定性,并观测了堤顶的越浪情况。为增强海堤挡浪墙的稳定性,对斜坡式海堤断面提出了两种调整方案:一种为改变挡浪墙形式、加大挡浪墙重量;另一种为优化斜坡式海堤海侧坡面的结构形式,抬高护面戗台及护面肩台的顶高程。结果表明,本试验中抬高海堤护面戗台及护面肩台的高度,使部分大浪在块石护面处破碎,减小了波浪对挡浪墙的作用力。增强挡浪墙的稳定性效果较好。

Experimental Study on Stability of Wave Wall of Rubble Mound Breakwater

Through model test to verify the stability of wave walls in various design plans and other parts of rubble mound breakwater under wave action, and observe the overtopping situation at the top of breakwater. In order to enhance the stability of wave wall, two adjustment schemes for the section of rubble mound breakwater are presented： one for changing the forrc~ ct- wave wall and increasing the weigh of it; another for optimizing the structural form of the side slope of breakwater, lifting up the crest elevations of armour berme. The results show that lifting up the crest elevations of armour berme, some of the huge waves are broken at the armour stone, the action force of waves to wave wall is reduced, the effect for enhance the stability of wave wall is good.
