摘　　要：数值实验已成为岩石力学教学与研究的重要手段,可以分析复杂岩石工程的变形和破裂规律,是岩石力学物理实验的重要补充。对岩石力学数值实验教学中复杂地质建模前处理方法进行了讨论。为了实现不同软件针对同一问题的模拟并相互验证,需要实现同一模型在不同软件间的转换。以ANSYS模型转换为FLAC模型为例进行阐述,以大岗山水电站双曲拱坝及含复杂地质体的坝基的三维数值建模工程为例进行了应用,并在石油大学"土木工程软件分析与应用"课程中进行了2年的实践教学,取得了良好的教学效果。Numerical tests have become an important means of teaching and research in rock mechanics,which can be used to analyze the deformation and fracture of rock,and becomes an important supplement of physics tests in rock mechanics.This paper discusses pre processing methods of complex geological modeling in the numerical tests teaching of rock mechanics.In order to verify the correctness of the simulation results by using different software,the same mesh model needs to be transformed between different software.The method in which ANSYS model converts to FLAC model is introduced,and three dimensional numerical modeling of Dagangshan hydropower arch dam containing complex geological structure is taken as an example.This content has been carried out for 2 years in the practical teaching for course of Civil Engineering Software Analysis and Applications in China University of Petroleum,which has achieved good teaching results.
