摘要
根据斜坡堤模型试验结果,给出拟合公式。再采用拟合公式、现有规范公式和研究者给出的经验公式,对斜坡堤不同堤顶高程下越浪产生的堤后次生波高值进行计算。对比计算结果与试验结果,可知拟合公式与试验结果最为接近;分析其他公式计算结果不吻合的原因。结果可为其他允许越浪斜坡堤在堤顶高程设计时的堤后次生波高计算和模型试验提供参考。
According to the results of a sloping seawall model test, we obtaine the fitting formula. Using the fitting formula, standard formula and empirical formula given by researchers, we calculate the secondary wave height produced by overtopping of the the sloping seawall under a different crest elevation, and compare the results with the model test, from which we know that the result by the fitting formula and test results are close most to each other; we also analyze the reason why the results from other fitting formulae are not consistent with the test result. The results may serve as reference for the secondary wave height calculation and model test of other slopping seawalls which allow the overtopping during the crest elevation design.
