摘要
基于弹性理论和地理信息系统 (GIS)技术 ,建立了用于开采沉陷预测的GIS面元栅格数字化模型 .模型可计算任意层面中任意点的位移、应力和应变 ,并利用GIS给出了实例研究的动态可视化结果 .该模型对任意开采形状和范围的开采沉陷预测具有高效、实用的价值 ,初步实现了开采沉陷预测的自动化、智能化和可视化 .
Based on elastic theory and GIS technology, the model of GIS raster digitized model with face element is established to predict mining subsidence. The model can calculate the displacement, stress and strain for any point in any overburden layer. Also the visual result is presented by means of GIS in the case study. The model is proven to be highly effective and particularly aimed at predicting subsidence at any point with any shape of excavation covering a wide range of mining geometry, providing automation, intellection and visualization in subsidence prediction.
