摘　　要：通过分析无线闭塞中心(RBC)的系统结构和功能,从RBC的角度辨识出各种安全风险,并将它们分为列车超速和列车冒进两大类;采用故障树分析方法对2类风险分别建立故障树,进而求解故障树的最小割集,识别出所有可能导致这2类安全风险的原因。分析结果表明,导致列车超速的直接原因一是RBC向列控系统车载设备发送了错误的行车许可信息或与速度相关的信息,二是RBC未能向列控系统车载设备发送应该发送的行车许可或与速度相关的信息;导致列车冒进的直接原因一是RBC发送了错误的行车许可或有条件紧急停车信息,二是RBC未及时发出缩短行车许可以及有条件和无条件紧急停车信息。针对分析和归纳出的五大类共11项安全风险原因,给出对应的防范措施,并经在武广高速铁路应用,验证了防范措施有效且实用。The safety related risks of radio block center （RBC） were recognized from the points of view of RBC by the analysis of the structure and function of RBC system. Two categories of safety risks called train over-speeding and train trip were concluded. The fault tree analysis （FTA） method was used to analyze the reason of the two categories of safety risks. Firstly,fault trees of them were constructed respectively. Then the least cut sets of the trees were solved,and all the reasons which could result in the two categories of safety risks were recognized. According to the result of analysis,the first direct reason of train over-speeding is the sending of the wrong movement authority （MA） or any other message in relation to the speed from RBC to automatic train protection system （ATP）,and the second direct reason is not sending the MA or any other message in relation to the speed which should be sent to ATP. The first direct reason of train trip is the sending of wrong MA or conditional emergency stop message （CEM） to ATP,and the second direct reason is not sending the shortened MA or CEM or unconditional emergency stop message in time. After the analysis and summary,11 reasons are concluded and divided into 5 categories,and then countermeasures are proposed for each of them. The application on the pilot line of Wuhan-Guangzhou high-speed railway demonstrates the effectiveness and practicability of the countermeasures.
