基于SURPAC的复杂岩体RFPA3D模型构建与应用

摘要 RFPA3D软件前处理功能薄弱，无法有效便捷地建立形态复杂的岩体模型，而采矿专业软件SURPAC具有强大的复杂地质精确建模能力，且两款软件模型单元均为六面体单元，以此作为研究基础，提出利用SURPAC软件快速准确地进行RFPA3D模型生成的方法.根据SURPAC块体单元和RFPA3D模型单元之间的数据关系，在MATLAB中编制以上两种软件的模型转换程序STOR.m;并在某露天铁矿挂帮矿开采边坡失稳分析中进行了应用.计算过程及结果表明，复杂岩体模型的转换高速便捷、准确可靠，同时拓展了RFPA3D和SURPAC的应用空间.
Abstract：Pre-processing function for RFPA3D is not so strong that rock mass model with complex geomorphology could not be effectively and conveniently built. While SURPAC， a professional mining software， has a strong ability in modeling complex geological body. Besides， the requirement of unit types for both two softwares is hexahedral. On this basis， a method to build the model in RFPA3D from SURPAC was proposed. According to the data relationship between the two softwares， a conversion program named STOR.m was developed in MATLAB to achieve the model conversion from SURPAC to RFPA3D. The program was used in a slope instability analysis model in an open pit iron mine. Results show that the model conversion method can be applied conveniently and extends the application of SURPAC and RFPA3D.
