摘要
目前对加固治理后的边坡健康状态,边坡加固结构的使用寿命与维护方面研究很少.针对既有加固边坡锚杆结构耐久性评价影响因素指标的灰色和模糊性问题,基于灰色关联度分析与模糊识别理论,建立既有加固边坡锚杆结构健康状态诊断方法,确立边坡加固锚杆结构健康诊断指标体系和指标评判基准,根据加固边坡锚杆耐久性评价的各项指标的变异程度,提出了基于信息熵和复合权重的评价指标融合赋权方法.研究结果表明:本文提出的既有加固边坡锚杆健康状态诊断方法能够全面系统地反映既有加固边坡工程的整体健康状态,评判结果可靠合理,从而为锚杆结构的设计、施工和维护提供了一定的参考价值,也为既有边坡加固工程的健康诊断提供了一种新的方法,具有重要的工程实际意义.
Few researches have been done on the health status of a reinforced slope,as well as on the service life and protection of reinforced structures in a slope at present.In view of gray and fuzzy index of durability evaluation influencing factors on anchors in an existing reinforced slope,this article sets up a health status diagnosis method and evaluation criteria of index system on anchors in an existing reinforced slope based on the theories of gray correlation and fuzzy recognition.We put forward a method of evaluation index fusion empowerment value based on information entropy and compound weight according to variation degree of durability evaluation indexes on anchors in an existing reinforced slope.Research shows that the diagnosing method of the health status of anchors in an existing reinforced slope proposed in this paper can reflect health status fully and systematically.Judgment results are reliable and reasonable as well,which provides new ideas and methods for the health status diagnosis of existing reinforced slopes and the design,construction and maintenance of anchors.It has an important significance and reference value in civil engineering fields.
