摘要
为了快速有效地分析边坡的稳定性,提出了利用模糊层次分析法对边坡稳定性进行综合评价,结合实际工程现场调查,确定了模糊层次分析评价指标、模糊隶属度函数和权重,最后建立基于模糊层次分析的边坡稳定性评价模型。根据模型对莆田学院西区边坡进行稳定性评价,并与传统的边坡稳定性分析方法进行对比。结果表明:模糊层次分析评价方法综合考虑了边坡的岩体完整性、岩体风化程度、岩土体力学性质、节理裂隙、岩层产状、断层分布及产状、边坡坡角、降水、地震及人类活动等影响因素,可以有效快捷地对边坡稳定性进行评价。
In order to quickly and effectively analyze the stability of the slope,a fuzzy hierarchical analysis method is proposed to conduct a comprehensive evaluation of the slope stability.Combined with the actual engineering site investigation,the fuzzy analytic hierarchy process evaluation index,fuzzy membership function and weight are determined,and finally,a slope stability evaluation model based on hierarchical analysis is established.According to the established model,the stability of the slope in the west area of Putian University is evaluated and compared with the traditional slope stability analysis.The results show that fuzzy hierarchical analysis comprehensively considers the influencing factors such as rock mass integrity,rock mass weathering degree,mechanical properties of rock and soil,joints and fissures,rock layer occurrence,slope angle,precipitation,earthquakes and human activities,etc.,and can effectively and quickly evaluate the slope stability.
