摘　　要：高速铁路速度目标值是高速行车技术的核心指标，采用模糊综合评判法对高速铁路目标值进行综合评判。从能耗、噪声、时间及优势距离4个方面分析对高速铁路速度目标值选择的影响，并且确定相应的参数值，将参数值带入数学模型，采用权重分析法引入权重，在考虑安全因素的基础上尽可能兼顾高速铁路综合效益最大化，最后建议在运营初期高速铁路目标速度值范围为200～250 km/h，运营成熟期高速铁路目标速度值范围为250～300 km/h。High-speed railway（HS） target speed value is the core index of HS train operation technology, this paper makes comprehensive evaluation on HS target value by using fuzzy comprehensive evaluation. From 4 aspects of energy consumption, noise, time and advantage distance, the paper analyzes the influence of the 4 aspects on selection of HS target speed value, and determines relative parameter values, and then the parameter values are brought into mathematical model and the weight is introduced by using weight analysis method. Based on considering safety factors, the maximized HS comprehensive benefits should be taken into account. In the end, the paper suggests that the HS target speed value in early period of operation should be 200~250 km/h, and the value in mature period of operation should be 250~300 km/h.
