当前国内外对地质体应用模型研究较多,由于专业方向不同、各类数据间的差异,其构建方法众多。本文选择两种方式,一是基于DEM插值曲面构建应用模型,动态演示年际地面沉降和地下水位变化,并对其成因、发展趋势等进行分析评价。二是选择具有空间插值性质的地质数据—视电阻率数值,构建应用模型,可以显示数据的空间展布,进行切割、开挖,以及等值面追踪等功能,进而根据其分布规律反向验证地质体模型中地层划分的正确与否。总之,应用模型与地质体模型的耦合,在地下资源的管理、展示、分析,地质灾害的风险评价,以及辅助管理部门决策等具体工作方面,有较强的应用性和实践意义。
At present, there are many researches on the geologic body application model both at home and abroad. Due to the difference of the professional direction and the differences among the various types of data, there are many construction methods. In this paper, we choose two methods. One is to construct an application model based on DEM interpolation surface to dynamically demonstrate interannual land subsidence and groundwater level changes, and analyze and evaluate its causes and development trends. The second is to choose the geological data with the property of space interpolation as the apparent resistivity value and construct the application model to display the spatial distribution of the data and carry out the functions of cutting, excavation and isosurface tracing, and then reverse verification according to the distribution rule The stratigraphic division in the geologic body model is correct or not. In a word, the coupling between application model and geologic body model has strong applicability and practical significance in specific work such as the management, display and analysis of underground resources, risk assessment of geological disasters and the decision-making of auxiliary management departments.
