高速铁路营业线“四电”施工准备阶段安全和质量管控措施研究

Study on Safety and Quality Control Measures in "Four Power" Construction Preparedness Stage of High-Speed Railway Business Line

自2003年10月12日我国第一条准高铁秦沈客运专线开通运营以来,高速铁路建设发展迅猛,仅2018年新增高铁营业里程约2500公里,截止2018年底我国高铁营业里程将达到2.9万公里。早期建设的高速铁路有部分线路面临大修,或者既有中间站接入新线改造。目前我国的高速铁路运营维护也在一步步实践探索中,目前还没有实施过完整的既有高速铁路站改工程。高速铁路营业线“四电”工程施工工程量大、工序繁琐、技术复杂、交叉施工环节多、牵涉面广、协作关系众多、安全风险大、施工现场安全质量控制难度大。本文借鉴普速铁路站改和高速铁路运营经验,来探讨高速铁路营业线“四电”工程的安全和质量管控。

Since the operation of the first quasi-high-speed railway Qinhuangdao-Shenyang passenger dedicated line on October 12,2003, the construction of high-speed railway has been developing rapidly. Only by 2018, the high-speed railway will be increased by about 2500 km. By the end of 2018, the high-speed railway will reach 29,000 km. In the early construction of high?speed railway, some of the lines are subject to major overhaul, or the existing intermediate station has access to the new line transformation. At present, the operation and maintenance of high-speed railway in China is also in a step-by-step practice. The construction quantity of the high-speed railway business line "four-electric" project is large, the process is complicated, The technology is complex, the cross construction links are many, the involved area is wide, the cooperation relation is numerous, the safety risk is great, and the construction site safety quality control is very difficult. Based on the experience of station reform and high-speed railway operation, this paper discusses the safety and quality control of the "four power" project of high-speed railway line.
