Abstract: Grey Correlation Model is employed analyze sensitivities of influencing factors. This model regards sensitive factors as sub-sequences, the corresponding safety factors as primary-sequences, top-difference as transforming method of basic data and correlative degrees as estimating indexes of sensitive factors. The model takes the Xiatudiling landslide which is located at Shuitianba, the area of the Three-Gorges reservoir as an example, and four influencing factors, respectively the cohesion of sliding zone(c), the angle of internal friction of sliding zone(φ), acceleration of earthquake and water level of the reservoir, are selected as sub-sequences and the safety factors, which are calculated by push method, are considered as primary-sequences. It is concluded that the values of C and φ are the most sensitive influencing factors of all of the factors.

Key words: grey correlation model, sensitivity, correlative degrees, push method
