摘要
为快速准确地识别边坡的稳定性,从多因素综合评价角度,提出了一种基于属性区间识别的边坡稳定性评价的新模型。在建立边坡稳定性评价体系的基础之上,采用AHP法和熵权法分别计算指标的主观权重和客观权重,采用最优离差组合赋权法计算各因素指标权重,并通过属性区间识别技术判别边坡的稳定性。算例表明,该模型能够获得与可拓方法、灰色理论一致的评价结果,可作为边坡稳定性评价的补充方法。
For identifying slope stability quickly and accurately, a new model for slope stability evaluation based on attribute interval recognition is put forward from the perspective of multi-factor comprehensive evaluation. After establishing slope stability evaluation system, the AHP method and entropy weight method are firstly used to calculate the subjective weights and objective weights of index parameters respectively, and then the final weights are obtained by using optimal combination empowerment deviation method, and finally the slope stability is identified by attribute interval recognition criterion. The engineering example calculations show that the results of new model can achieve same evaluation results with extension model and grey theory. The new method can be used as a supplement in slope stability evaluation.
