Abstract: In the process of high-speed railway construction, there is no experience and lack of practice in the standardization assessment of information engineering, it has always been a weak link. To solve these problems, based on the author’s practical work experience, this article introduced the contents of the standardization assessment, such as evaluation preparation, implementation and summary. The evaluation method, evaluation content, evaluation criteria and so on were expounded. These contents of the standardization assessment were applied to the Baoji-Lanzhou high-speed railway information engineering, achieved significant effect. The standardization assessment can maximize the investigation of hidden trouble exists, improve the overall construction quality of the information project, ensure the use effect.
