Grey Correlation Method is employed to analyze the sensitivities of factors influencing slope stability.The matrix of correlation data is set up

the elements of which are then transformed to dimensionless parameters using top-difference transforming method.The grey correlative factors and grey correlative degrees between the influencing factors and the safety factor are computed

and the sensible factors influence slope stability are then determined.This method has been applied in a slope reinforcement project in Fujian province.The influencing factors such as unit weight

cohesion

internal friction angle

groundwater level

slope height as well as slope angle are considered.The sensitivity of slope stability is analyzed with the above-mentioned factors being taken as independent and dependent respectively.The result shows that internal friction angle and cohesion are the principal susceptive factors influencing the slope stability

on the basis of which effective reinforcement measures are put forward.
