Abstract: Visual C++ was used as development software to virtually simulate the 3D aquifer structure and groundwater table surface of Suzhou-Wuxi-Changzhou area. They are visualized with the help of OpenGL at the same time. The aquifer structure and groundwater table from many optical perspectives were easily observed. It is convenient to study the relationship of strata at different positions, the hydraulic connection of different aquifers, the spatial distribution of groundwater table and the horizontal positions of recharge region and discharge region of groundwater. At the same time, the dynamic evolution of groundwater table surface is realized which can be used to explore the temporal and special variation of groundwater table surface.

Key words: virtual reality, OpenGL, 3D geologic structure, groundwater table surface
