摘　　要：针对礁盘地形上波浪运动形态的复杂性及相关防波堤工程设计中的结构稳定性问题,对礁盘地形附近某工程及相关海域的海床地形进行模拟,并通过波浪整体物理模型试验验证工程区防波堤堤脚的稳定性情况。试验结果表明:礁盘地形上堤脚块石稳定重力若按规范计算偏危险。研究结合试验现象及结果对堤脚进行优化,提出礁盘地形上防波堤堤脚开槽的优化方案。In consideration of the complexity of wave movement from near reef terrain and the difficulty of breakwater’s design near this kind of terrain,a project near the reef terrain and related seabed terrain is simulated,and the stability of breakwater’s toe rock is verified by physical model test.The test results show that it is dangerous to calculate the weight for stability of toe stones on reef terrain according to the codes.Based on the experimental phenomena and results,the optimum design of breakwater toe grooving on reef terrain is proposed.
