艰险山区铁路建设质量安全红线问题统计分析

Statistical Analysis on the Safety Events of Railway Construction in Mountainous Areas

摘要: 由于艰险山区地形地质条件复杂，艰险山区铁路建设常面临着桥梁隧道占比高、线路高差大、设施设备维护难度大等问题，施工难度大、安全风险高。本文对成昆铁路复线米攀段和峨米段建设过程中的质量安全问题进行统计分析，指出艰险山区铁路建设施工各阶段应重点关注的质量安全问题，为艰险山区铁路建设质量安全管理提供借鉴。

Abstract: Due to the complex terrain and geological conditions in mountainous areas, railway construction often faces problems such as a high proportion of bridges and tunnels, large line elevation differences, and difficult maintenance of facilities and equipment. The construction is difficult and safety risks are high. This paper analyzes the safety events during the construction of the Miyi-Panzhihua section and Emei-Miyi section of the Chengdu-Kunming railway line. It points out the quality and safety issues that should be paid attention to at each stage of railway construction in mountainous areas, and provides reference for the quality and safety management of railway construction in mountainous areas.
