摘　　要：选取南京某地铁线路典型岛式站台进行了屏蔽门漏风量测试,得出了屏蔽门漏风量的变化趋势,并建立三维模型对漏风量进行了数值模拟,与实测数据进行了对比,分析了列车停站期间漏风量的变化规律。定量分析了漏风量对车站空调负荷的影响,最后对车站环控系统的运行提出优化建议。Taking one typical underground island station in Nanjing as a study object, the air leakage quantity of platform screen doors was test, and the changing rules of air flow was concluded. To compare the field test results and analyze more deeply, a three-dimensional CFD model was built and the detailed simulation was carried. Based on the results, how the air flow changed was analyzed when the train stopped and the influences of air leakage quantity on the air-conditioning load were analyzed. At last, advice for optimizing the operation of environmental control system was proposed.
