山区公路崩塌灾害隐患危险性评价方法研究

摘要

以G109国道门头沟段崩塌灾害隐患为例，提出运用定性和定量相结合的方法，对山区公路崩塌灾害隐患进行稳定性评价。根据山区公路发生的崩塌灾害，可能造成的损失大小难以定量化估计的情况，将损失大小用危害程度来代替。应用层次分析-模糊数学评价方法，对崩塌灾害可能造成的危害程度进行了定量评价。%This paper takes the G109 in Mentougou section of national highway landslide hazard as an example, and adopts the qualitative and quantitative methods to evaluate the stability of landslide of highway in mountainous area. According to the landslide of mountainous highway, it may cause the loss of the quantitative estimates of the size, and the size of damage degree may replace the loss. Application of analytic hierarchy process and fuzzy evaluation method may be used to evaluate the damage degree of the landslide.
