Abstract: | Vast data from the drilling and geophysical prospecting are reliable original information to describe the space state of engineering
rock mass, and one of the main difficulties in three-dimensional (3D) modeling of engineering rock mass is the processing
of the primary data. From the view-point of 3D modeling, the engineering rock masses are classified as four basic types according
to their geometric characteristics of geologic structure: (1) continuum rock mass; (2) discontinuous rock mass; (3) overturned
fold rock mass and (4) intrusive rock mass. Because drilling data are very important to describe the characters of multi-scale
of the spatial data for rock mass, the rule of how to process drilling data is developed to help appropriately display them
in the viewpoint of 3D space. According to the characteristics of rock mass layers, the processing method of drilling data
for 3D modeling of engineering rock masses, along with the layer thicknesses, is also proposed, including the evaluation rules
and the extensive direction for original borehole data. By this method, the typical 3D data modeled is completed and the model
form of the engineering rock mass is developed. By this example, it is finally verified that the method presented is successful
and feasible to process 3D engineering rock mass.
