摘要
常用的边坡稳定性影响因素敏感性分析方法是假设其中某一个因素变化,其它因素不变,而在实际中 这种单一因素发生变化的情况是很少的,大多是多因素共同变化。根据正交设计的特点,将正交试验设计应用 到边坡稳定性影响因素敏感性分析中,并以具体边坡为例进行了分析,将分析结果与传统的单因素分析方法所 得的结果进行比较,表明基于正交设计的边坡稳定性影响因素敏感性分析是可靠的,而且实现了多因素共同变 化,计算量也得到减少。
The commonly used method for analyzing the sensibility of the factors affecting slope stability needs an assumption that only one factor changes while other else keep fixed. In reality, however, such condition is seldom. Orthogonal design is used in the analysis of the sensibility of the factors affecting slope stability. One specific slope as an example is analyzed with orthogonal design before a comparison is made between its result and the traditional one-factor analyzing method. As the new method realizes a joint change of various factors, the analysis of the sensibility of the factors affecting slope stability based on orthogonal design is much more reliable.
