摘要

由于Surpac软件本身功能的限制，基于Surpac块体模型的三维数值建模技术在处理复杂矿山地质形体时存在费时、繁琐等缺陷。通过沿用八叉树层层细分的基本思路，研究了多个地质形体的网格批量自动划分技术，针对现有计算机处理能力在解析精度与模型尺度方面存在的矛盾，借用多重网格法概念探讨了网格局部加密和多尺度划分问题。并应用VC++开发了三维数值网格划分自动化软件平台，使复杂矿山地质形体的计算网格划分更加便捷高效，为开挖力学状态数值分析的自动化提供有力支持。该系统在玲珑金矿原始地应力反演数值建模中得到了实际应用，结果表明，该方法是实际可行和有效的。

Abstract

Due to the limit of Surpac software

the method for 3D numerical grid generation based on the Surpac software generally suffers for some deficiencies such as time-consuming and cumbersome. By adopting the basic idea of octree subdivision

the batch and automatic meshing technology of multiple geological body is investigated. To resolve the confliction issue arising when both the precision and the model scale need to be considered in computation

the grid local encryption and multi-scale partitioning methods are introduced and discussed based on the concept of multiple grid method. An automation software platform is developed for 3D numerical grid generation by using VC++. The platform can be conveniently and effectively used to generate the numerical grids for the mining fields with complex geomorphology

providing a strong support for the automation of excavation numerical analysis. The new platform has been used in the in-situ stress inversion analysis of Linglong gold mine

showing its applicability and capability.
