土墙的安全状况直接关系到铁路运输系统的安全，如何评估既有挡土墙的安全状况是亟待解决的问题。为了准确评估挡土墙安全状况，指导工程实践，建立了一种新的铁路既有线挡土墙安全评估指标体系，体系包括表观状况，材质状况，受力状况三大一级指标，和包含墙身，墙顶，裂缝，砂浆等10项在内的二级指标。该指标体系的优点是结合定性与定量，层次分明；为克服传统安全评估方法的主观性等不足，提出了层次分析－模糊数学综合安全评估方法，达到评估结果量化的目的；并结合实际工程进行了既有线挡土墙安全现状评估体系研究，结果表明该方法能给挡土墙较为客观的总体评估。

The safety situation of retaining wall is directly related to the safety of railway transportation system.Evaluation of the safety of the retaining wall is a problem urgently to be solved in.In this paper,the safetyevaluation index system of retaining wall on the existing railway is established.It includes surface view of status,material status,and force status.These status are level indicators.It also includes wall body,wall,cracks,mortarand other six projects.They are the secondary indicators.The index system has the advantages of distinct,and thecombination of qualitative and quantitative.In order to overcome the subjectivity of traditional safety assessmentmethods,the analysis hierarchy process and fuzzy mathematical comprehensive safety assessment method are putforward.The method quantifies evaluation results.The result of the research of safety assessment system of retainingwall combining practical engineering shows that the method can give the retaining wall a more objective overallevaluation.
