基于模糊层次综合评价法的高边坡安全风险预测

High Cut Slope Safety Hazard Prediction Using Fuzzy Analytic Hierarchy Process Method

以贵阳市黄山冲的某小区住宅楼7#、8#、9#基坑开挖形成的高边坡工程为例,利用专家调查法结合信心指数法对边坡存在的安全风险及其影响因素进行了识别,建立了该城市高边坡工程安全风险的评价模型,利用层次分析法和模糊层次综合评价法对建立的风险模型进行了分析,得出该边坡工程的安全风险等级,最后针对评价结果提出了风险管理对策建议。

This paper presents the hazard evaluation results of three excavation slopes for Buildings#7,#8and#9in a residential development in Huangshanchong of Guiyang City.The safety hazard and its influence factors of these high cut slopes are evaluated by a combination of Expert Investigation Method and Confidence Index Method.The engineering safety hazard model for urban high cut slopes is established and the model is evaluated with the Analytic Hierarchy Process（AHP）as well as Fuzzy Comprehensive Evaluation（FCE）.The safety level of these slopes are obtained and the risk management recommendations are proposed.
