摘要 瓮马铁路南北延伸线是促进贵州经济发展的又一重大工程,在查明区内地质环境条件、道路沿线及周边影响范围内地质灾害的类型、规模、分布特征、形成因素及其危害程度的基础上,开展地质灾害危险性现状评估。结果显示,研究区可分为地质灾害危险性大区和地质灾害危险性中等区两种级区,其中地质灾害危险性大区总长145 588. 8 m,对工程建设的危害程度大;地质灾害危险性中等区总长299. 45 m,对工程建设的危害性较大。 The north-south extension of the wengma railway is another major project to promote the economic develop of guizhou province.On the basis of ascertaining the types and scale distribution characteristics of geological disasters along the road and in the surrounding areas of geological environment conditions,forming factors and their harm degree,the risk status of geological disasters is evaluated.result showed:The study area can be divided into two levels:large geological hazard area and medium geological hazard area.The total length of the large geological hazard area is 145588.8m,which has a high degree of damage to engineering construction.The total length of the middle area of geological hazard is 299.45m,which is more harmful to engineering construction.
