摘　　要：对日本近期铁路轨道技术研究成果文献资料进行介绍和梳理分析,发现其研究方向主要聚焦在人口老龄化、少子化等社会环境条件下的轨道设备低成本、少人化、省力化的养护维修技术。日本铁路轨道研究借助现代数字仿真模拟、超声波探测等技术开展的轨道基础性技术研究成果,为轨道相关应用研究提供了支撑。近年来,我国在线路轨道维护机械化、自动化、信息化、智能化的基础性和应用技术研究方面取得了大量成果。由于我国面临与日本社会环境类似的相关问题,日本铁路轨道基础性技术研究的方向和成果可为我国铁路轨道技术研究工作提供参考与借鉴。This paper introduces,sorts out and analyzes the results of recent research on railway track technology in Japan,and finds that its research mainly focuses on low-cost,flexible-manpower-line and labor-saving track maintenance and repair technology under the social and environmental conditions featuring aging population and low birth rate.The results of the fundamental research on track technologies carried out in Japan with the help of modern digital simulation,ultrasonic detection and other techniques provide support for track-related application research.In recent years,China has made great achievements in the fundamental research and application research on mechanized,automated,information-based and intelligent track maintenance technologies.Since China is faced with the situation similar to Japanese railways,the research direction and achievements of Japan’s fundamental research on railway track technologies can provide reference for China’s research on railway track technologies.
