摘　　要：敏感性分析是滑坡稳定性研究的一个重要方向。介绍敏感性分析的基本定义,并列举多种敏感性分析方法。正交设计法作为一种多因素敏感性分析法,不仅具有正交性、代表性,而且计算过程简便、次数较少,因而采用正交设计理论,以东庄库区滑坡实例为依托,对影响滑坡稳定的重要因素进行敏感性分析,找出影响滑坡稳定性的主导因素,对滑坡防治具有十分重要的现实意义。Sensitivity analysis is an important research direction of landslide stability. The paper introduces the basic definition of sensitivity analysis, citing variety of sensitivity analysis methods. Orthogonal design as a multi - factor sensitivity analysis, which not only has the orthogonal representation, and the calculation process is simple, less frequently. Therefore the authors use orthogonal design theory research based on specific project examples, find out the dominant factor affecting landslide stability and minor factors. It is of great practical significance for landslide control.
