基于灰色关联法的涉水边坡稳定性影响因素敏感性分析
Sensibility Analysis of Influencing Factors of Reservoir Slope Stability Based on Grey Correlation
摘要
Abstract
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, permea-bility 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 er-rors 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.关键词
