Abstract: Aiming at safety monitoring and 3D visualization expression of rock blocks in underground powerhouse of hydropower engineering, we established a 3D visualization monitoring software of rock blocks by using BIM+ 3DGIS technologies.The monitoring software can reflect space information of blocks and geometric shape in high-resolution terrain scene, also it candisplaylocation of monitoring gauges, incorporate the BIM model of workshops and associate monitoring data, realizing pre-warning for blocks in 3D visualization environment.The monitoring software has greatly improved the effectiveness of safety monitoring in right-bank underground workshop in the Three Gorges Hydropower Station.The relevant experience could provide some referential values for the 3D visualization monitoring and management of the water resources and hydropower projects.

Key words: underground powerhouse; stability of blocks; safety monitoring; BIM+3DGIS;
