Abstract:
stability is influnced by many factors.It is necessary to study the sensitivity of influence factors of slope stability. By using reasonable computational model, and grey correlation grade method to analyze the main influence factors of the high loess slope stability in Baojixia Water Division Project. The results indicate that the angle of internal friction and cohesion are the principal factors influencing the slope stability; and by the method of orthogonal test, the results indicate that the influence of earthquake is also significant on the slope stability. All the results show that the angle of internal friction and cohesion are the principal factors influencing the slope stability; on the basis of which shearing strength should be correctly and reasonably selected. And the influence of slope height and earthquake also should be considered. Therefore, the study can provide reference for high slope of loess design, operation and management.
Key words: high loess slope, grey correlation grade, orthogonal test
