摘　　要：针对目前能力分析方法存在列车运行间隔与设计间隔差异很大的问题,本文提出了借助计算机单车仿真及作图解析法来分析城轨移动闭塞正线通过能力的方法。该方法结合信号系统ATP/ATO控车模型进行单车仿真和能力分析,借助作图解析法进行分析,同时考虑了联锁或运营限制条件对能力造成的影响。通过设计间隔计算结果与实测结果对比可以看到,实测结果与设计间隔的平均误差为0.4 S。数据表明,运用该方法可以得到接近实际的分析结果。Considering the problem of difference between operation spacer and design spacer, the paper proposed a method based on single train simulation and mapping anaiysis to analyze the method for carrying capacity of mainline in Moving Block System of Urban Transit. The method combined the actual train control model of ATP/ATO to simulate a single train and analyze the capacity with the help of mapping analysis method, meanwhile considered the influence to capacity caused by interlocking and condition of operating limitation. Comparing with the design spacer and actual measurement, the average error was 0.4 second. The data showed that the result was closed to the actual soacer with this method.
