摘　　要：文中以季冻区铁路路基工程为例,将路基的安全等级划分为安全、较安全、危险和极危险四个等级,采用1-9标度法确定各级评价指标权重。基于层次分析法,选择季冻区路基差异沉降三级评价指标,建立风险评价模型,确定相应风险等级,结合锦承铁路现场路基工程现场监测数据,对季冻区路基差异沉降进行了定量评价。评价结果与实际情况一致,说明该方法可应用于季冻区路基差异沉降风险评价。This paper illustrates seasonal frozen ground railway subgrade engineering.It categorizes subgrade safety into four levels:safe,relatively safe,dangerous,and extremely dangerous.Using a 1-9 scale,it determines evaluation criteria weights.Employing the Analytic Hierarchy Process(AHP),it selects a three-level assessment for seasonal frozen ground subgrade differential settlement and establishes a risk assessment model.Finally,using on-site monitoring data from the Jincheng railway subgrade project,it quantitatively assesses differential settlement in the seasonal frozen ground subgrade.The assessment aligns with actual conditions,affirming the method's applicability for risk assessment of differential settlement in seasonal frozen ground subgrades.
