Abstract Research purposes: Hungary-Serbia Railway in Serbia is mainly designed according to European Union's standards and Serbian standards. In order to promote Chinese standards to go global, the following aspects are compared with Chinese standards: track and train load, profile and width of subgrade surface, structure of subgrade bed, subgrade filling material and compaction criteria, slope protection, drainage engineering of subgrade, retaining structure and subgrade settlement control. The differences in the main design technical standards of the Chinese and Serbian railway subgrade are put forward to study the applicability of Chinese standards in railway subgrade engineering in Serbia.
Research conclusions: (1) The standards of China and Serbia have made different provisions on track and train load, profile and width of subgrade surface, structure of subgrade bed. The design of railway subgrade needs to be based on Serbian standards. (2) In terms of subgrade filling material and compaction criteria, slope protection, drainage engineering of subgrade and subgrade settlement control, the standards of China and Serbia are similar. And the Chinese standards have made more detailed classification and design provisions, which are applicable in Serbia. (3) The standards of China and Serbia are two sets of different design methods and theories in the design of retaining structures. The Chinese standard adopts the combination of allowable stress method and limit state method for the design of retaining structures. The safety factor and partial factor are summarized from the continuous practice in the process of railway construction in China, but lacking the experience of application in Serbia. (4) The research results can provide reference for the application of Chinese standards in the design of Serbian railway subgrade.
