该项研究分别采用规则波与不规则波两种试验方法，通过有胸墙及无胸墙潜堤的对比试验，从不同角度对汕头深水港外导流防沙堤的稳定性进行了论证。试验结果表明，规则波的试验结论与实际情况不符，在不规则波作用下原设计断面是不稳定的，其失稳率远超出了允许的标准。潜堤及设置了胸墙的潜堤均有其特殊性不能用一般斜坡堤及无胸墙潜堤的标准去判断有胸墙潜堤的稳定性。本文就潜堤设计与试验中的有关技术问题进行了探讨，有关试验成果为确定最终的设计断面提供了依据。
In this study, two methods, regular wave and irregular wave, were used respectively to test the stability of Diversion-proof sand-dam outside Shantou’s deep-water port from different perspectives. The experimental results show that the experimental conclusion of the regular wave is not in accordance with the actual situation, and the original design section is unstable under the action of the irregular wave, whose instability rate far exceeds the allowable standard. Submarine and the setting of the chest wall of the submarine has its own particularity can not be used to the general slope of the slope and the non-chest wall submerged embankment criteria to determine the stability of the chest wall with a submerged embankment. In this paper, the technical problems in the design and test of submerged embankment are discussed, and the relevant experimental results provide the basis for determining the final design section.
