摘要
Abstract
The stability of landslide is influenced by many factors. The sensitivity of influencing factors on landslide stability can be classified and their significances can be tested through sensitivity analysis. Taking Xiatudiling landslide for example, five influence factors were chosen and sensitivity analysis was performed based on the brief introduction to the orthogonal design theory. The results of the range analysis and variance analysis indicated that the sequence of the sensitivity from big to small is: internal frictional angle of slip soil φ, cohesion of slip soil c, groundwater level of landslide H, earthquake acceleration coefficient a, bulk density of landslide body y, among which the first four are highly significant factors and bulk density of landslide body has no remarkable effect on landslide stability.关键词
