Abstract: Currently, the deep excavation monitored dada are not systematically catgorized and standardized, therefore, a large amount of monitored data are potentially wasted since the data cannot be shared. In order to form a standardized coding system for the deep excavation monitored data, the The current deep pit monitoring information has not form a certain standard yet, the data cannot be shared, which cause a lot of waste of monitoring data. In order to form a unified coding standard, on the basic of the current monitoring standards and the research of the previous, in the case of the monitoring data of Changzhutan railway Xiangfu road pit, the monitoring data has been classified, and the paper propose the standard of the monitoring classification and coding, utilizing the most advanced spatial geodatabase technology to manage the monitoring data and design of the database table. At last, based on the .NET framework and C# development language, and the ArcGIS Engine 10.2 is used as the development platform, the management system of the database is developed to achieve the information management of the monitoring data.
