中国高速铁路轨道设计标准在东南亚地区的适应性研究OA北大核心

South Asian countries have not yet established a local high-speed railway standard system.Countries where the"the Belt and Road Initiative"cooperation projects are located,such as Indonesia Yavan High-speed Railway and Thailand Bangkok-Nakhon Ratchasima high-speed railway,are all based on the technical standards of China's high-speed railway.Due to different national conditions,China's high-speed railway standards cannot be directly applied to high-speed railway projects in Southeast Asia.Based on the specific cases of Indonesia Yavan High-speed Railway and Thailand Bangkok-Nakhon Ratchasima High-speed Railway Project,this paper analyzes the adaptability of China's high-speed railway track design standards in Southeast Asia from the aspects of the main design principles,engineering materials,rail sizing,track structure selection,prefabricated track slab,and continuous welded rail.The main conclusions are as follows:(1)The reinforcement and concrete can be made of local materials,which should be reasonably selected by comparing the strength,chemical element content and other characteristics.(2)The steel rails in Southeast Asian countries and regions are generally imported from China.Therefore,the sizing of rail needs to take into account the influence factors such as port hoisting infrastructure,existing marine conditions,overseas road and railway transportation,and 50 m rail is recommended.(3)In combination with local climate conditions,the ballastless track structure shall be reasonably optimized from the perspective of economy,and the ordinary reinforced concrete track slab can be used.(4)The technology of China's seamless line technology can fully adapt to the line conditions in Southeast Asia.
