摘　　要：轨道交通中道岔的技术性能及岔区的建筑限界设计直接影响运营组织效率和车辆运行安全,针对重庆市轨道交通6号线工程中应用曲线道岔的情况,依据曲线道岔参数及布置形式,利用图解法模拟车辆过岔过程,并进行加宽量计算,拟合出道岔区建筑限界的加宽量图,讨论曲线道岔区建筑限界加宽量的影响因素及计算方法,为岔区土建、结构设计提供理论依据。The technical performance and structure gauges design of turnout in urban rail transit system can affect operation organi zation efficiency and the safety of train operation directly. Based on the application of curve turnout in Chongqing Metro Line 6, widening value is calculated with graphic method by simulating the train passing through the turnout according to the parameters and arrangement form, and then the fitting graph of widening value for structure gauges in turnout area is obtained. Finally, some influ- encing factors and calculation methods of the widening value are put forward. The research can supply a theoretical basis for civil engineering structure design in turnout area.
