%X Orthogonal experiment and grey correlation analysis method are coupled to make sensitivity analysis on six main influence factor for a homogeneous slope in reservoir area using GeoStudio-based limit equilibrium analysis method. The sensitivity of slope stability factors ranks in the order of internal friction angle, cohesive force, permeability coefficient, rate of reservoir water level drawdown, slope angle, and degree of declining in reservoir water level. The combination of orthogonal design and grey correlation method could, to a large extent, eliminate the errors generated by tests by taking the interactions among factors into consideration, and could also overcome the shortcomings of traditional mathematical statistics analysis. The results offer reference for the support of reservoir slope and prevention works.
