摘要
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,开展地质体三维数值模型构建方法比较研究具有重要意义。以FLAC3D数字化模型为基础,提出了FLAC3D-Rhino耦合建模方法,详细阐述了各建模方法具体步骤。构建了桂林市五美路停车场商住楼深基坑土方开挖及工程三维数值模型,分析了深基坑上开挖地层位移和水压的变化,研究成果对准确构建地质体三维数值模型具有重要指导作用。
The construction of three-dimensional numerical model of real geological body is a difficult problem for the numerical analysis of rock mass engineering. It is of great significance to carry out a comparative study of the construction method of three-dimensional numerical model of geological body. Based on the FLAC3 D digital model, a FLAC3 D-Rhino coupling modeling method is proposed and the detailed steps of each modeling method are elaborated. Three-dimensional numerical model of excavation and engineering for deep excavation of commercial parking building of Wumei Road parking lot in Guilin City was constructed. The change of excavation stratum displacement and water pressure in deep excavation was analyzed. The research results have important guiding role in accurately constructing three-dimensional numerical models of geological bodies.
