【摘要】 以阿里地区国道219线巴尔至札达公路沿线地质灾害为研究对象,通过调查研究公路沿线的地质灾害,采用灰色聚类法,选取地层岩性、地面坡度、相对高差、构造密度、多年平均降水量、冻融作用、地震强度、植被覆蓋率、开挖深度、灾害的分布密度和规模大小等11个评价因子,给出了各因子对应评价级别的基准划分值,建立了地质灾害危险性级别的评价模型,得出了公路沿线地质灾害的危险性级别。更多还原

【Abstract】 Taking the geological hazards along the highway from No.219 national road to Zanda in Ali region as the research objects,On the basis of out-site inspection and detailed analysis of geology data,the paper put forward a model for assessment of geological hazards by means of grey cluster analysis with 11 assessment factors such as lithologic character,slope,relative difference of elevation,structural density,mean annual rainfall,freeze thawing,earthquake intensity,vegetation cover rate,excavation depth,hazard density and scale,and definited the criterion of the evaluation factor and given the criterion value of the corresponding factor.The paper obtained the level of geological hazards along the highway.更多还原
