Abstract: With the comprehensive study of the existed data of hydropower engineering, and considering their distributed characteristics, a method of 3D geologic body modeling based on grid partition is proposed. Due to the difference of ground surface data and geologic data, two different partition algorithms are proposed accordingly, namely, contour partition based algorithm of ground surface data and partition algorithm of geologic data based on the distributed feature of drill data; and edge matching method is used to solve of fracture caused by partition. After establishing the model of 3D geologic body, considering the feature of grid partition, a quick excavation algorithm based on grid partition is presented; and the advantage of grid partition based geologic model over the traditional geologic model is also analyzed. Finally, to test the correctness and feasibility of grid partition based on geologic modeling, an empirical study of a hydropower project is conducted.

Key words: geologic body, grid, partition, 3D, rapid excavation
