基于SURPAC的复杂岩体RFPA^(3D)模型构建与应用

RFPA^(3D) Modeling and Application for Complex Rock Masses Based on SURPAC

RFPA^(3D)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RFPA^(3D)模型生成的方法.根据SURPAC块体单元和RFPA^(3D)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RFPA^(3D)和SURPAC的应用空间.

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 RFPA^（3D）.
