【摘要】 滑坡稳定性受多种因素影响,对滑坡稳定性影响因素进行敏感性分析非常必要。介绍了均匀设计的基本原理及特点,并将均匀设计试验方法引入到滑坡敏感性分析中,利用试验点在试验范围内的均匀分布,大大减少了试验次数。研究表明,在常见的均质土坡或松散堆积体岩土质边坡中,摩擦角φ和粘聚力с为最敏感因素;在抗震设防烈度为7度以下的一般岩土体地区,土的重度γ和地震加速度a为不敏感因素。更多还原

【Abstract】 Landslide stability is influenced by many factors. It is necessary for us to study the sensitivity of influence factors of landslide stability. Uniform Design’s postulate and characteristic is introduced, and this experiment method is brought in to analyze the sensitivity of influence factors of landslide stability. With uniform design, the times of experiment are reduced. Four influence factors, respectively the density of soil (γ) , angle of internal friction (φ) , cohesion (с), acceleration of earthquake(a), are selected as the safety factors. It is concluded that the values c and φ are the most sensitive influencing factors of the four factors above, and the density of soil(γ) and acceleration of earthquake(a) are the insensitive influencing factors.更多还原
