波浪作用下灌砌块石海堤的护面稳定性

通过物理模型试验,对一种新型的海堤护面结构形式——灌砌块石护面的稳定性进行研究,总结了波浪作用下灌砌块石护面失稳破坏的发展过程。研究结果表明:灌砌块石稳定性随破波参数的增大而减小、随开孔率的增大而增大,同时镇压层的设置有利于提高灌砌块石的稳定性。结合前人关于砌石护面稳定性的研究成果,给出了不同开孔率下灌砌块石护面稳定厚度计算公式。

Stability of grouting and masonry armor of seawall under wave action

A physical model test is carried out to study the stability of a new type of seawall called grouting and masonry armor.The development process of the instability of the grouting and masonry armor is studied under wave action.Research shows that the stability of the grouting and masonry armor decreases with the increase of the breaking wave parameters and increases with the increase of the opening rate.Similarly,the setting of the suppression layer is conducive to increasing the stability of the grouting and masonry armor.Based on the previous research results,the formulas for calculating the stability thickness of the grouting and masonry armor with different opening rates were given.
