摘要
构建反映真实地质体的精细化数值计算模型是数值模拟分析的关键。以3DMine软件的优秀三维地质模型构建能力为基础,提出了一种多软件耦合(3DMine-Rhino-HyperMesh)的数值模型建模方法,解决了露天矿高陡边坡三维地质与数值统一模型构建难题,并详细阐述了该建模方法的具体步骤和思路。以攀枝花某露天采场为工程背景,构建了反映真实地质体矿区的精细化数值模型,并分析了矿场边坡的潜在破坏机制。结果表明,该建模方法构建出的模型与真实地质体产状对应性较好的同时,提高了数值模型网格质量,对构建大型复杂地质体数值模拟计算分析提供了一种新的建模思路。
Constructing a refined numerical calculation model that reflects the real geological body is the key to numerical simulation analysis.Based on the excellent three-dimensional geological model construction ability of 3DMine software,a numerical model modeling method of multi-software coupling(3DMine-Rhino-HyperMesh)was proposed,which solved the problem of three-dimensional geological and numerical unified model construction of high and steep slope in open-pit mine.The specific steps and ideas of the modeling method were described in detail.Taking an open pit in Panzhihua as the engineering background,a refined numerical model reflecting the real geological body mining area was constructed,and the potential failure mechanism of the mine slope was analyzed.The results show that the model constructed by this modeling method has a good correspondence with the real geological body,and improves the grid quality of the numerical model,thus providing a new modeling idea for the numerical simulation calculation and analysis of large-scale complex geological bodies.
