In order to reduce the total energy consumption of mountain railway engineering from the design source,optimize the energy consumption structure,give full play to the advantages of railway green development,it is very important to carry out energy-saving research on mountain railway engineering and identify the key elements of energy-saving design of mountain railway engineering.Firstly,analyzed the energy consumption of mountain railroad engineering,sorted out the key points of energy saving of mountain railway lines,bridges,tunnels and other key projects.On this basis,extracted the energy-saving design elements and energy consumption elements of mountain railway engineering.According to the characteristics of each element,the quantitative indicators were defined,and the energy consumption elements and index system of mountain railway engineering were established.Secondly,the CRITIC-entropy power method and C-OWA operator method were combined to construct a two-layer complex network model of mountain railway engineering-energy consumption,and determine the nodal importance of each element.The intensity of influence between nodes and the comprehensive importance of nodes were obtained to identify the key elements of energy-saving design of mountain railroad engineering.Finally,taking a bid section of a major railway project in a mountainous area as an example,the method model was verified and the key factors affecting the energy-saving design in the construction stage of the bid section were identified:tunnel operation equipment selection,tunnel slag control,tunnel ventilation mode selection.The key factors can affect the energy-saving design in the operation stage are:curve radius setting,line longitudinal slope setting,line slope setting,energy-saving slope setting,passenger station heating design,passenger station shape design.It is verified that the energy consumption elements and index system of mountain railway engineering conform to the characteristics of mountain railway engineering.The complex network model of mountain railway engineering-energy consumption has good applicability.The key elements of energy-saving design and its optimization suggestions can provide reference for energy-saving design of mountain railway engineering.
