摘　　要：波浪爬高是防波堤堤顶高程设计和预估工程造价的重要影响因素.以防淤积型透空式防波堤为研究对象,采用1∶10的模型比尺,在64组不同工况下开展防波堤的物理模型爬高试验,并记录了不同工况下防波堤迎浪侧的最大波浪爬升高度,探究了防波堤的波浪爬升特征.分别运用多项式回归方法、速度水头方法与M5'模型树算法并结合物理模型试验波浪爬高结果,发展透空式防波堤波浪爬高的预测公式.利用统计参数对3种方法发展的预测公式进行对比分析.结果表明:透空式防波堤背浪侧的波面变化滞后于迎浪侧,其最大波浪爬高小于迎浪侧,防波堤具有良好的消波效果;采用多项式回归方法与速度水头方法发展的预测公式能够在一定程度上实现对防波堤波浪爬高的预测,前者仅考虑了波高而忽略了其他波浪条件及防波堤结构参数对波浪爬升高度的影响,后者对波浪爬高的预测结果与试验值偏差较大,二者在实际应用过程中都存在一定的局限性;M5'模型树算法发展的波浪爬高预测公式利用无量纲参数综合了各项波浪要素以及防波堤的结构参数等,拥有良好的统计指数,能够更好地预测透空式防波堤的波浪爬高,具有较高的实际应用价值.Wave run-up is an important factor influencing the elevation design and project cost estimation of breakwater.In this paper,an anti-deposited permeable breakwater was taken as the research object,the physical model run-up experiment of the breakwater was carried out under 64 different working conditions with a model scale of 1∶10,and the maximum wave run-up height on the wave side of the breakwater under different working conditions was recorded,thereby exploring the wave run-up characteristics of the breakwater.The prediction formulas for the wave run-up of the permeable breakwater were developed using the polynomial regression method,velocity stagnation head method and M5'model tree algorithm respectively combined with the results of the physical model experiment,which were further compared and analyzed by means of statistical parameters.First,results show that the wave surface change on the back side of the permeable breakwater lags behind that on the wave side,and the maximum wave run-up on the back side is less than that on the wave side,indicating that the breakwater has a satisfying wave dissipation effect.Second,the prediction formulas developed by the polynomial regression method and velocity stagnation head method respectively can predict the wave run-up of breakwater to a certain extent.The former only considers the wave height but ignores the influences of other wave conditions and the breakwater’s structural parameters on the wave run-up height,while the latter has a large deviation between the prediction results and experimental values of wave run-up,indicating that both have certain limitations in practical applications.Third,the wave run-up prediction formula devel-oped by the M5'model tree algorithm uses non-dimension parameters to integrate various wave parameters and the breakwater’s structural parameters,so it has good statistical indexes and can better predict the wave run-up of the per-meable breakwater,which is of high practical application value.
