Abstract
Steel blade angle advance support is a new protection system for the existing railway lines, of which basic principle is to implement grid for face section and break it down into elements, so as to facilitate the operation and improve traffic safety. Taking a bridge as an example, the paper describes the working mechanism of steel blade angle advance support, its advantages and disadvantage, stability calculation, line reinforcement and anti-pull system settings, and so on. For turnout area which is not suitable for temporary beams ( or cross beams ) , or stations with large investment for line protection, electrified railways and high embankmens, steel blade angle advance supportt is well adapted, which provides good solution for existing railway lines to carry out large-scale interchange project.关键词
