摘　　要：依托琼州海峡海底电缆抛石工程,以重力相似准则进行抛石极限稳定性的水工物理模型试验,获取块体稳定重量、抛石坝形状、抛石级配等极限设计参数。结合试验结果,对抛石块体重量、抛石坝形状等参数进行分析,提出了海底电缆抛石保护的若干设计建议并用于工程实践。Based on the Qiongzhou Strait submarine cable rock dumping project, this paper researches the ultimate stability of the dumping rock by hydraulic physical model tests rely on the gravity similarity criterion, in order to obtain the ultimate design parameters such as stable weight of rock, the shape of rock dam, and rock gradation. After combining the result of hydraulic test, and analyzing parameters such as the weight of rock, shape of rock dam, this paper proposes some suggestions about the protection of submarine cable, and provides references for practical engineering application.
