摘要

Railway structures have been constructed since the old age compared to road structures. They have been bearing the safe and stable operation of the railway so far, which has been made possible by a proper management of their maintenance. However, even in an important line, railway structures exceeding 70 years in age after construction can be seen. While there are high needs of railway structure repair and reinforcement technology, the renewal technologies of railway structures including their function improvement are being demanded. Therefore, this review describes an overview of the current state of railway bridges and viaducts and introduces the recent research and development trends of the renewal technology of bridges and viaducts developed by Railway Technical Research Institute.
