高速铁路的GSM-R通信无线覆盖的可靠性分析是保证列车安全、高效运行的技术手段之一。抽象出胶济线GSM-R网络结构，利用故障树分析法，根据各个网络节点的可靠度，计算出整个系统的可靠度。胶济线GSM-R网络覆盖采用单网交织冗余覆盖方案，铁路沿线基站设置的比较密集，根据故障树定量分析法，求出顶事件发生概率的近似值，根据某厂家提供的相关产品参数，得到GSM-R网络主要单元节点的可靠度预测值。

The reliability analysis of GSR-M wireless communication coverage on high speed railway is one of the technical means to ensure safe and efficient train operation. This paper abstracts GSR-M network structure on the Qingdao-Jinan Railway Line, and calculates the reliability of the whole system with fault tree analysis based on the reliability of each network node. Single layer network redundant coverage is applied to fulfill GSR-M network coverage on Qingdao-Jinan Railway Line, and base stations are set up intensively alongside the railway. According to fault tree analysis, approximate values of the probability of top events occurrence are obtained. In accordance with the relevant product parameters provided by a supplier, the predicted values of reliability of the main unit nodes of GSM-R network are worked out.
