针对计算机模拟中的关键问题，即三维地质体的剖分和体积计算方法进行了较深入的讨论。在将地质体剖分为内部单元和边缘单元之后，又将内部单元细分为中间的长方柱体和两端的不规则多面体。通过分析，给出了计算内部单元和边缘单元不规则多面体的体积计算公式，并通过对两种理论模型的剖分和计算结果，说明了方法的正确性和提高精度的有效性
Aiming at the key problem in computer simulation, that is to say, the method of dividing and calculating the volume of three-dimensional geological body is discussed in depth. After the geological body is divided into internal units and edge units, the internal units are subdivided into rectangular columns and irregular polyhedrons at both ends. Through the analysis, the formula for calculating the volume of the irregular polyhedron of the inner cell and the edge cell is given, and the correctness of the method and the effectiveness of the accuracy are illustrated through the analysis and calculation of the two theoretical models
