层次分析法评价降雨对万塘滑坡稳定性的影响
首发时间:2009-04-23
摘要:利用层次分析法建立了万塘滑坡危险度评价模型,综合考虑降雨、地震、人类工程活动、库水位、地形地貌、地层岩性和岩层组合结构七个方面的因素,对三峡库区万塘滑坡进行危险度评价,并与传统的刚体极限平衡法相比较验证。通过重点定量分析降雨对万塘滑坡稳定性的影响程度,验证了降雨在滑坡稳定性中所起的关键作用,为滑坡灾害预防提供依据。

Analytic hierarchy process in assessment influence of rainfall on Wan tang landslide stability
Abstract:Based on analytical hierarchy process, the text establishes a risk assessment model of Wan tang landslide. Considering the seven combinations of factors of rainfall, earthquakes, human engineering activities, water level, topography, litho logy and rock structure, the text carries out a risk assessment of Wan tang landslide. And make a compare with traditional rigid body limit equilibrium method. By focusing on analysis of rainfall on Wan tang landslide degree of stability, the text proves the key role of rainfall in the landslide stability. It provides a basis for warning of landslide.
Keywords: analytic hierarchy process Rainfall Wan tang landslide Stability
