Lanzhou-Xinjiang High-speed Railway is the first high-speed railway opened in western China. The surrounding natural environment has the characteristics of high altitude, cruel cold, large temperature difference between day and night, windy and dusty, etc. Based on the theory of railway infrastructure gridding management, this article discussed the business requirements of permanent-way risk management of Lanzhou-Xinjiang High-speed Railway, used the information technology to built the permanent-way risk management information system of Lanzhou–Xinjiang High-speed Railway. The position of permanent-way risk was identified within the range of 200 meters, implemented the transition from qualitative to quantitative change in the risk assessment of permanent-way safety. The business requirements, the framework design, the database design, the data interface and the functional design of the system were emphatically discussed.%兰(州)新(疆)高速铁路是我国西部第一条建成通车的高速铁路,周边自然环境具有高海拔、严寒、昼夜温差大、风沙大等特点.文章基于铁路基础设施设备网格化管理理论,深入分析兰新高速铁路工务安全风险管理的业务需求,利用信息技术研究构建兰新高速铁路工务安全风险管理系统,将工务安全风险发生位置定位在200 m之内,实现工务安全风险评定从定性化到定量化的转变.重点论述该系统的业务需求、技术架构、数据库设计、数据接口方案及系统主要功能.
