经过2012 年洪水后, 大连市碧流河部分堤段堤顶高程已达不到原设计标准, 必须进行修复改造, 而堤顶超高 的计算是确定堤顶高程的前提, 风浪爬高的计算是确定堤顶超高的前提。根据大连市碧流河水库下游金哨桥至入 海口河段堤防的风场要素特点, 选用SMB 法公式和莆田试验站公式计算了该河段堤防的波浪爬高和堤顶超高, 并 与该河段堤防的实际工程应用值以及东北地区内陆河流域的实际设计值进行对比, 分析了这两种方法计算结果的 合理性, 为该河段堤顶高程的确定提供依据。

After the flo od in 2012, the crest elevations of some dams cannot meet the design standards in the Biliuhe River of Dalian; ther efor e it is necessary to r ebuild these dams. Calculation of dike levee fr eeboar d is the premise of the determination of dike crest elev atio n, and calculation of wave run2up is the pr em ise of the determinatio n of lev ee freeboar d. Acco rding to the char2 acter istics of w ind field elements o f the dike and Jinshao Br idge t o the mo ut h of Biliuhe Reservo ir in Da lian, the SMB method formula and Putian ex per iment stat ion formula w ere selected to calculat e the wav e r un2up and lev ee fr eeboa rd. The results wer e compar ed w ith the actual eng ineering data in the r iver sectio n and design data o f inland r iver s in nort heast, the r eliability of the results obtained fr om the tw o methods w as ana lyzed, w hich can pr ov ide the basis for determinat ion of the dike cr est elevation.
