真实地质体三维数值模型构建是进行岩体工程数值分析面临的难题，开展大型复杂地质体三维数值模型构建方法比较研究具有重要意义。以3DMine数字化模型为基础，提出了3DMine-FLAC3D耦合建模方法和3DMine-Surfer-Rhino- ANSYS-FLAC3D多软件耦合建模方法，详细阐述了各建模方法具体步骤，深入分析了各建模方法优缺点及适用性，通过对比各建模方法的优势与短板，取长补短，改进了3DMine-FLAC3D耦合建模方法存在的缺陷，解决了复杂地质体三维数值模型构建难题。以广西铜坑矿锌多金属矿体开采为背景，利用大型复杂地质体三维数值建模方法，构建了锌多金属矿三维数值模型，分析了矿体上行开采地表沉陷规律。研究成果对准确构建大型复杂地质体三维数值模型具有重要指导作用。

Abstract

3D numerical model construction of real geological body is the challenge faced by numerical analysis in rock mass engineering

resulting in that the comparative study between different constructing methods of 3D numerical models of large and complex geological body has great significance. Based on 3DMine digital model

the coupling modeling methods of 3DMine-FLAC3D and 3DMine-Surfer-Rhino-ANSYS-FLAC3D are put forward; and then the concrete steps of every modeling method are described in detail. Besides

the advantages

disadvantages and applicability of every modeling method are further analyzed. Through contrasting the advantages and short boards between each modeling method and learning from each other

the defects that exist in coupling modeling method of 3DMine-FLAC3D are improved; and the constructing problem of 3D numerical model of complex geologic body is solved as well. With the background of zinc-polymetallic ore body in Guangxi Tongkeng Mine

the 3D numerical modeling method of large and complex geologic body is utilized to construct the 3D numerical model of zinc-polymetallic mine and analyze the surface subsidence law for ascending mining. Research achievements play an important guiding role in accurately constructing the 3D numerical model of large and complex geological body.
