防波堤护面六角型多孔块体的试验研究

Test Study on Hexagon Multihole Armour Block on Breakwater

本文介绍了一种新型的斜坡式防波堤护面块体——六角型多孔块体,它具有嵌固性好、抗浪能力强、节省混凝土的特点.通过水工模型试验,给出稳定性与波高、周期、水深、坡度、摆放方式、孔隙率、垫层情况的关系,及重量对稳定的影响,给出了块体设计计算方法和相应公式.

This paper introduces a new kind of armour block - hexagon multihole block on sloping breakwater. It has great characteristics such as good interlocking, strong resistance against waves and saving concrete. Through the hydraulic model test, the mechanism of stability of the block has been proved and the relations between stability and wave height, wave period, water depth, slope, laying method, porosity and padding have been obtained. The effect of weight on steadiness have also been found. Finally, the method of design and some formulas are given.
