摘要
对滑坡的危险性进行评价并提出防治措施能有效的减缓滑坡灾害带来的损失.以广东省滑坡危险性评价为例,选取地形地貌、地层岩性、地质构造、岩土体结构、水文地质条件、植被覆盖率、降雨分布、地震以及人类经济工程活动等9个评价因素,通过改进的层次分析法得出因素权重的大小,清楚地显示出主要因素和次要因素.结果表明:地层岩性影响最大,岩土体结构次之,植被覆盖率最小.结果对滑坡的危险性评价提供了更科学、合理的依据.
Evaluation the risk of landslide and Taking corresponding prevenUve measures coum inm^tt~ u~ losses caused by landslide hazards.Taking Guangdong Province as an example, we did the landslide hazard evaluation, using 9 types of affecting factors, which are strata topography, formation lithology, geologic structure, rock-soil structure, hydrogeology condition, vegetation coverage, rainfall, earthquake and human engineering activity. And then the weights for screened evaluation factors are determined based on improved analytic hierarchy process, which clearly indicate main factors and subordinate factors, and the chief good is strata topography, rock-soil structure the second, vegetation coverage the last. The results show that this method is reasonable and feasible for landslide hazard risk assessment.
