主客观权重及其在边坡稳定性综合评价中的应用

Subjective and objective weights and their application on slope stability comprehensive evaluation

目的:探讨综合评价中指标权重的确定.方法:将客观属性赋权法和主观重要性排序法相结合来确定指标权重,并应用于土质边坡稳定性的综合评价.结果:对文中的10个边坡的稳定性做出了正确的评价;结论:主客观权重法既充分利用了样本资料的统计信息,又反映了专家的理论知识和经验,可得到较为客观、合理的指标权重,将此权重用于综合评价,其结果准确可靠.

Objective：to discuss the determination of index weight in comprehensive appreciation.Method： to combine the objective weighting method and subjective importance ranking method to determine index weight,which is used in the comprehensive evaluation of soil slope stability.Result： to correct evaluations of slope stability on 10 slopes mentioned in this paper;Conclusion： the application of subjective and objective weighting method,both making the best use of statistical information from samples and taking experts’ theories and experience,can obtain reasonable index weight,with which used in the comprehensive evaluation,correct results are secured.
