摘要
边坡稳定性是受多种因素作用影响的复杂系统,对其进行合理、准确的评价一直是岩土工程研究的重要内容。基于灰关联分析法,将灰色关联度原理引入边坡稳定性分析中,并考虑到边坡稳定等级标准中各因素取值的区间形式,提出了边坡稳定性等级评价的方法。以某实际边坡为例,对各影响因子进行关联度分析,进而得到边坡的灰关联度排序,最后依据最大关联度原则,确定边坡的稳定性级别。算例分析表明,改进的灰关联度分析法,作为一种工程地质的类比方法,对边坡稳定性的分析是合理而有效的。
The stability of rock-mass slopes is a very complicated system which is controlled by lots of factors.It is always a very important research subject to evaluate the slope stability reasonably.Based on the gray correlation analysis method,the principle of the grey relational grade is applied to evaluate the stability of rock-mass slope,and the method of the stability of rock-mass slopes is proposed by considering the numerical interval of the stability of grade.The example shows the improved gray correlation analysis method is reasonable and feasible.
