摘　　要：本文以粤港澳大湾区城际线路佛山经广州至东莞城际工程陈家林车辆段地块为研究对象,针对传统DRASTIC模型指标关联性、主观性强,评分值缺乏连续性等缺陷,依托地铁车辆段工程场地实际条件,该模型采用全定量评价指标体系,评价指标更加客观合理;使用三标度层次分析法确定各评价指标权重,减少了传统DRASTIC模型人为确定权重的主观性;引入模糊数学理论,克服了传统DRASTIC模型使用定额评分带来的不连续性。模糊综合评价结果表明:研究区浅层地下水防污性能整体表现为差-较差,占研究区总面积的97.21%。研究结果可为佛穗莞城际陈家林车辆段浅层地下水污染防治工作提供科学依据。This article takes the Chenjialin depot plot of the Guangdong Hong Kong Macao Dawan intercity Line Foshan to Dongguan intercity project as the research object.Aiming at the shortcomings of the traditional DRASTIC model such as strong correlation and subjectivity of indicators,and lack of continuity in scoring values,and relying on the actual conditions of the subway depot project site,the model adopts a full quantitative evaluation index system,making the evaluation indicators more objective and reasonable;Using three scale analytic hierarchy process to determine the weight of each evaluation index reduces the subjectivity of traditional DRASTIC models in manually determining the weight;The introduction of fuzzy mathematics theory overcomes the discontinuity caused by the use of quota scoring in traditional DRASTIC models.The results of fuzzy comprehensive evaluation indicate that the overall performance of shallow groundwater in the study area is poor poor,accounting for 97.21%of the total area of the study area.The research results can provide scientific basis for the prevention and control of shallow groundwater pollution in the Chenjialin depot between Foshan and Guangzhou.
