摘　　要：通过对水流挟冰花能力建立的冰塞壅水计算方法的研究,对有实测冰塞观测资料的万家寨河段率定的经验公式的经验系数进行了分析,找出了与河段平均比降、断面宽、综合糙率的相关关系,进而推求了无实测冰塞资料的海勃湾河段的冰塞壅水水面线,并从冰塞图形、计算成果两方面论证了成果的合理性。It analyzes the empirical coefficient of empirical formula calibrated by using Wanjiazhai section where has observed data of ice jam,finds out the correlativity of the mean slope,width of cross section and synthetic roughness of the section,computes the surface curve of ice jam damming of Haibowan section where has no observed ice jam data and proves the rationality of the outcome from two aspects of ice jam graph and calculation results through the study on the established calculation methods of flow with frazil slush capability.
