THE EXPERIMENTAL STUDY OF ACCROPODE UNIT STABILITY OF BREAKWATER SUBJECTED TO OBLIQUE WAVES

For breakwater construction. the armour unit stability of breakwater is one of most important factors to be considered by engineering designer In general. the armour unit stability under normal incident waves is paid more attention than that under oblique incident waves by designers according to regular engineering criterion In this paper, a series of physical model test were carried out to examine the accropode unit stability of breakwater under normal and oblique incident wave actions According to the experimental results, it can be found that the accropode units on breakwater become more unstable under oblique incident waves than that In normal incident waves in the same wave conditions h is suggested that when the breakwater length is long enough. the accropode unit stability under oblique waves attack should be paid more attention than the normal incident case The results of this study may give it good reference for breakwater design of the accropode unit stability in waves
