【摘要】 影响边坡工程稳定性的因素众多而复杂,影响程度各不同,问题具有不完全性、非确定性的特点。基于灰色系统理论的灰色关联分析原理,选取影响边坡稳定性的主要因素,如重度、粘聚力、内摩擦角、边坡角、边坡高度、孔隙水压力比等,建立了应用于边坡稳定性分析的灰色关联度法。给出的应用实例,其评价结果与实际情况一致,说明边坡稳定性灰色关联度分析法的有效性。更多还原

【Abstract】 The influencing factors of slope stability are numerous and complex,with different influencing degrees,which are incomplete and uncertain.In this paper,based on grey correlation analysis of grey system theory,the main influencing factors of slope stability such as specific gravity,cohesion,inner frictional angle,slope angle,slope height,and pore water pressure ratio are selected to establish grey correlation method for slope stability analysis.The evaluation result of the given application example conforms to the actual condition,which indicated the validity of grey correlation method in slope stability analysis.更多还原
