摘　　要：桥梁总体技术状况评定过程比较复杂,现场检测的过程中（分值为0～100）细微的分值差异就可能造成桥梁等级的变化.文章采用模糊层次分析法分析出桥梁总体技术状况的主要影响因素为上部承重结构、桥墩和上部一般构件;用模糊判断矩阵的0和1来代替100分制的打分系统,降低了得分的随机性;并通过实例进行了实际运用.Bridges overall technical condition assessment process is comparatively complex. Subtle scoring differences in field test may cause chan ges in levels of bridge. With the Fuzzy Analytical Hierarchy Process （FAHP）, the article finds out the main factors affecting the overall technical condition of the bridge, which are upper bearing structure, general members of piers and the upper part. What＇s more, the article uses fuzzy judgment matrixes 0 and 1 instead of 100-point scoring system so as to reduce the score randomness. Using this method to practical examples.
