摘　　要：相对贵州省其他公路线而言,三穗-贵阳高速公路地质灾害发生更频繁、危害更严重。结合自然地理地质条件和地质灾害特征,选定8项评价因子,采用黄金分割法确定其权重;运用综合分析的因子叠加法,对贵州省三穗-贵阳高速公路地质灾害进行了危险度分段评价。评价结果包括：高危险度段（岑松镇-三颗树）,中高危险度段（三穗-岑松镇）,中危险度段（谷脚镇-贵阳、三颗树-下司镇）,中低危险度段（黄丝镇-三元镇）,低危险度段（三元镇-谷脚镇、下司镇-黄丝镇）。The geological hazards along the Sansui-Guiyang Expressway take place more frequent and endanger is more serious than other highway lines in Guizhou Province. According to the natural geographical, geological conditions and hazardous features, 8 assessment factors are chosen to construct the assessment factor system. The weights of these factors are decided by golden section method. Through factor superposition method, assessment on danger degree division of geological hazards along the Sansui-Guiyang Expressway in Guizhou Province is carried out. The result shows that the high danger degree high-way section is in Censong-Sankeshu, the middle-high danger degree highway section in Sanhui- Censong, the middle danger degree highway section in Gujiao-Guiyang and Sankeshu-Xiasi, the middle-low danger degree highway section in Huangsi-Sanyuan, and the low danger degree highway section in Sanyuan-Gujiao and Xiasi- Huangsi.
