采用均匀设计试验方法可以用较少的试验点获得最多的信息。以三峡库区生基包滑坡为例，采用均匀设计方法研究了滑带土体重度γ、黏聚力C和内摩擦角φ对滑坡稳定性的影响。采用MATLAB软件进行逐步回归分析，建立多元回归模型，并对模型进行了显著性检验。结果表明：黏聚力C和内摩擦角φ对边坡的影响是显著的，且内摩擦角φ是主要影响因素，在滑坡治理中要主要控制黏聚力C和内摩擦角φ的值；土体重度γ对滑坡稳定性影响不显著，可以忽略。

Uniform design can get the most information with less sites. Taking Shengjibao landslide in Three Gorges Reservoir area for an example, the sensitivity of the soil parameters (weight of soil,cohesion and internal friction angle)affected landslide stability was discussed with uniform de-sign method. It built multiple regression model and conducted significant tests by using stepwise regression of MATLAB software. The results show that cohesion and friction angle have a significant impact on the slope,and the internal friction angleφare the main factors. So it should be primary control of cohesion and internal friction angle in the landslide control. Weight of soil has a little effect on landslide stability and can be ignored.
