本文介绍用正交极差分析的方法来评价边坡稳定性影响因素敏感度等。按正交表要求,随机选取各因素在实际研究边坡的可变化区间内的水平值,其计算结果不仅可以判明各影响因素的主次,而且可由每一影响因素与安全系数的关系曲线,判明影响因素取值对安全系数的影响趋势,并预计各影响因素取值对边坡稳定性所产生的系统响应。
In this paper, the method of orthogonal difference analysis is introduced to evaluate the sensitivity of slope stability factors. According to the requirements of orthogonal table, the level of each factor in the practical study slope can be randomly selected. The calculation result not only can determine the primary and secondary factors of each influencing factor, but also can be calculated by the relationship curve of each factor and safety factor, The influence of factors on the safety factor is identified and the systematic responses to slope stability are estimated.
