【Abstract】 In this paper,the earthquake damage information data about highway system in our country were gathered and complied,and the main damage mode of each research object in highway system was derived based on the statistical data of the gathered information.In combination with specifications and literatures in relevant field at home,the seismic damage classification method of highway system was supplemented and perfected in view of the defects existing in the working standards.At last a new seismic damage classification method for highway system is established which can give a reference to earthquake disaster loss evaluation for post-earthquake field works.更多还原
