英文摘要：

The visualization for the structural planes of rock tunnels provides an effective measure to study the stability of the rock. Here, based on the block theory and combining VC ＋ ＋ 6.0 with OpenGL images on the basis of existing modeling methods, the three-dimensional network simulation is made for the structural planes of rocks by using discontinuity network diagram. Such functions as the modeling, display and geometrical move of the rock tunnel are realized, as well as the computer searching and image display of the key blocks. The application results show that the method is simple and reliable, and has the three-dimensional display function.
