摘　　要：为了评估高速铁路的沿线地面沉降风险,建立新的犹豫模糊二元语言-数据包络分析(DEA)模型.该方法根据犹豫模糊二元语言计算理论处理评估意见,基于最大群体共识度原则调整专家权重,采用DEA模型确定因子权重,弥补以往评估方法一致性检验难通过、评估过程难度高及评估人员共识度低的缺陷.将犹豫模糊二元语言-DEA分析模型应用于安徽省淮北正在建设的某高铁工程,构建灾害因子、易损因子和敏感因子的风险评估指标体系,建立个体犹豫模糊评价集合和群体犹豫模糊评价矩阵,求得各因子权重.基于GIS系统实现灾害性、易损性和敏感性指标区域风险分布的可视化展示,得到高铁沿线地面沉降风险分布.结果表明,DK66-DK67为风险最高区段,须加强该区段的沉降监测.A new hesitant fuzzy 2-tuple-data envelopment analysis(DEA)model was established in order to assess the risk of land subsidence along high-speed railway.Assessment opinions were handled with the computation theory of hesitant fuzzy 2-tuple linguistic model.Experts’weights were adjusted based on the principle of maximum group consensus,and the factors’weights were determined by using the DEA model,which made up for the defects of the previous assessment methods,such as difficulty of passing consistency test,difficulty of assessment process,and low degree of consensus of the evaluators.The hesitant fuzzy 2-tuple-DEA analysis model was applied to a high-speed railway project under construction in Huaibei,Anhui Province.The risk assessment index system of hazard factors,vulnerability factors and sensitivity factors was established.The fuzzy assessment set of individual hesitation and matrix of group hesitation were established,and weight of each factor was obtained.The visual display of risk distribution in the disaster,vulnerability and sensitivity index assessment area was realized based on GIS system.Land subsidence risk distribution along the high-speed railway was obtained.Results show that DK66-DK67 is the highest risk section,and the subsidence monitoring in this section should be strengthened.
