河岸边界条件和河流动力条件是影响岸滩稳定的关键因素,为了探讨多种因素对岸滩稳定性的影响与评价,通过分析枯水期和洪水期岸滩稳定性的主要影响因素及差异,建立了河流岸滩崩塌影响因子的层次结构模型,利用层次分析法给出了枯水期和洪水期各主要影响因素的权重系数,指出无论在枯水期还是在洪水期,各主要影响因素对岸滩稳定性的作用具有很大的差异,进而提供了岸滩稳定性评价的新思路。
河岸邊界條件和河流動力條件是影響岸灘穩定的關鍵因素,為瞭探討多種因素對岸灘穩定性的影響與評價,通過分析枯水期和洪水期岸灘穩定性的主要影響因素及差異,建立瞭河流岸灘崩塌影響因子的層次結構模型,利用層次分析法給齣瞭枯水期和洪水期各主要影響因素的權重繫數,指齣無論在枯水期還是在洪水期,各主要影響因素對岸灘穩定性的作用具有很大的差異,進而提供瞭岸灘穩定性評價的新思路。

The bank boundary condition and the river dynamic condition are the key influence factors on bank stability .In order to study roles and evaluating method of many influence factors on the bank stability ,a hierarchical framework model is established through analyzing differences among main influence factors during the dry period and the flood period ,and weight coefficients of the main influence factors are given using the Analytic Hierarchy Process (AHP ) under corresponding conditions . It is pointed that the role of each factor in the bank failure process is much different whether in the flood season or in the dry season .A new idea evaluating the bank stability is given based on the AHP .
