Research on the Maintenance and Management Mode of High-speed Railway Infrastructure in China

Abstract

China has preliminarily built a modern high-speed railway network, and the huge scale of the network has put forward higher requirements on infrastructure maintenance and management. In order to achieve high quality and efficient development of high-speed railway, this paper conducts research on the maintenance and management model of China's high-speed railway infrastructure. This article describes the characteristics of infrastructure maintenance management in developed countries of high-speed railways such as Japan, France and Germany; summarizes the technical characteristics of China's high-speed railways and analyzes the factors influencing infrastructure maintenance management in China. Based on the theory of organizational structure, the article systematically analyzes the differences in the work content, work methods, and means of high-speed railway infrastructure inspection and monitoring, routine maintenance, and specialized repair operations, so as to put forward the maintenance management mode of the separation of "inspection, maintenance, repair". This model mixes together the specialization of technical management and the comprehensive integration of production organization. On this basis, a comprehensive maintenance system for high-speed railway infrastructure was designed and a comprehensive maintenance organizational structure and working mechanism was proposed. Practice has shown that a comprehensive maintenance system for high-speed railway infrastructure is conducive to improving emergency response capabilities, reducing operating costs and achieving optimal resource allocation.
