基于AHP的铁生沟滑坡风险评估研究

AHP-Based Risk Assessment of Tieshenggou Landslide

根据对铁生沟滑坡的长期监测结果,依据滑坡灾害产生的各种内在因素和外部条件,采用层次分析法建立了层次结构模型,计算出了该滑坡的危险度;经提取人口、经济发展及环境指标,对其进行易损度计算,综合评价该滑坡属高风险地质灾害.

Tieshenggou landslide is a large scale landslide with huge potential danger. On the basis of long term observation , according to the inherent geological factors and triggering conditions, an analytical hierarchy model was established by means of AHP method, thus the danger intensity of the landslide was obtained. Vulnerability concerning the landslide was calculated by referring to the factors such as population, economic development and environment. Taking into account the above calculation results,a the conclusion is got that the risk level of the landslide is high.
