Abstract: Reservoir engineering construction has high requirements for the work of geological specialty. How to accurately show the specific image of the complex survey results and improve the readability and availability of the survey results documents is a direction of the current water conservancy survey industry. In this paper, the AglosGeo 3D geological system developed based on Microstation platform is used to conduct 3D geological modeling of a reservoir dam site, analyze, evaluate and summarize the modeling process, and study the applicability and advantages of 3D geological technology in reservoir projects. Through the research, it is found that the 3D geological technology can cover the geological condition information in the database, make the 3D geological model has geological information attributes, and can carry out a series of analysis and calculation, so that the geological results can be better understood and used by relevant designers.3D geological technology will be able to change the general view of geological difficulty, become an indispensable part of the survey field, and even become an advantage part of the survey field.
