Study On The Construction And Maintenance Management Integration Of Heavy Haul Railway Based On Life-Cycle

Heavy haul railway of our country experienced the start, speed up the construction of the network, the appropriate scale, built in the development stage, the bottleneck effect of railway gradually eased, and the concentration of construction has brought a huge debt burden, on the one hand affect the sustainable development of the heavy haul railway construction, on the other hand, it also has great impact on the operation and management. For a long time, the disorder of the management system, blind decision, enterprises, the lack of the concept of full life cycle, the negative influence to the development of quality and efficiency is not high gradually. In this historical background, to carry out the research on the life cycle management of heavy haul railway, to help establish the concept of full life cycle, improve the level of project management, play an important role in the comprehensive benefits of the project.In this paper, the development status of heavy haul railway in our country, comparing to the characteristics of the heavy haul railway project construction and operation management, find out the difference of. According to the factors affecting the life cycle are analyzed, and through the comprehensive consideration of various factors, the establishment of multidimensional heavy haul railway total life cycle management system model, including system structure, elements, the project life cycle process of three dimensions, as well as between the various dimensions of comprehensive planning, comprehensive control, integrated management and other specific content. On the basis of this model, put forward three level management model includes the management decision-making, implementation and operation management and site management, were clearly the scope of task and work division and interface, and the establishment of organizational structure, the form of the whole life cycle management function and coordination channel, key control points of focus investigate, improve the quality and level of the whole life cycle management. The innovation of this paper lies in the influence factors on the life cycle management is analyzed, a system model of life cycle management, put forward three level project management system.The purpose of this study is to promote the management departments at all levels to fully understand the current situation and development trend of project management, is necessary to understand the practice of the concept of full life cycle, and the perspective of the integration of organization management mode and quality control measures of the whole life cycle of heavy haul railway, scientific decision-making, careful planning and design, high quality, high efficiency operation implementation heavy haul railway, to achieve sustained, healthy and steady development, to maximize the economic and social benefits, and provide useful reference guide.
