摘要
通过对溜砂坡稳定性的影响因子采用层次分析法进行定性分析,建立了溜砂坡致灾因子层次结构图。根据判断矩阵计算出溜砂坡各致灾因子的影响权重,建立了溜砂坡危险度评价指标,对溜砂坡的致灾因子进行了定量评价,并结合公路沿线实际情况确定危险度等级,为溜砂坡的预警及治理提供了依据。
In this paper,the analytical hierarchy chart of impact factors for sand-sliding slope is constructed by means of qualitative analysis.Based on the pairing comparison matrix,it calculates the weights of each hazard factors for sand-sliding slope,and the standard of hazard degree assessment has been established,with the quantity evaluation to the impact factors of sand-sliding slope.Along with the actual situation of landslide,it identifies the hazard degree,which will provide some references for warning and control of sand-sliding slope.
