印尼KARANG TARAJE港防波堤工程波浪整体模型试验研究

Wave model test research on breakwater engineering of KARANG TARAJE Port,Indonesia

采用不同波向及重现期波浪作用,对印尼KARANG TARAJE港防波堤进行了三维稳定性与越浪量测试,试验中各段护面块体均可保持稳定,而各水位重现期50 a最大越浪量为10 L/(m·s),满足设计不超过10 L/(m·s)的要求。与二维波浪水槽试验结果进行对比,稳定性结论一致,但越浪量存在较为明显的差异,在设计高水位时,二维断面试验的越浪量比三维试验结果大约30%,在极端高水位时其差异更大,甚至达到了50%。

Under the action of waves with different wave direction and return period, we carried the 3-D stability and overtopping rate tests for the breakwater of KARANG TARAJE Port, Indonesia. In the test, the armor block in each section can remain stable, and the largest wave overtopping rate is about 10 L/（m·s） under the wave condition of 50 a, this value meet the requirement of no more than 10 L/（m·s）. Compared with the experiment results of 2-D wave flume, the conclusion of stability is same, but there is obvious difference for overtopping. For the design high water level, the overtopping of 2-D model test is about 30%larger than 3-D, for the extreme high water level, the gap become larger, and even reached about 50%.
