Abstract:The archives management of the Reconstruction and Expansion of Water Diversion Project from the Yellow River to Qingdao adopts a three- dimensional collaborative mechanism of "system + technology + personnel", achieving a 96.9% archive integrity rate and 98.5% accuracy rate, which supports the project to be rated as "excellent". The realization of standardized archives management follows such paths as the parallel advancement of organizational management and system construction, the coordinated promotion of full- process control and informatization construction, and the dual strengthening of facility guarantee and quality control. In the practice of archives management, experiences such as "three inclusions", "three synchronizations" and "three dimensions" have been formed. In view of the existing problems, it puts forward improvement directions such as accelerating special acceptance and archives compilation, expanding in- depth application of informatization, and improving long- term mechanisms and dynamic management, providing a reference example for archives management of similar projects.
