Sufer和ArcGIS软件在大屯矿区地面沉降危险性评价中的应用

运用Sufer和ArcGIS软件对大屯矿区地面沉降危险性进行评价,在评价过程中发挥了Sufer强大的插值功能和ArcGIS良好的图像处理功能。由评价结果可获得地面沉降对砖石结构建筑物破坏等级,以及各个等级的破坏面积。指出应根据不同破坏程度处理建筑物破坏问题。同时,为控制地面沉降,应控制超采地下水。

Application of Sufer and ArcGIS Software in Risk Evaluation of Surface Subsidence in Datun Coal Mining Area

Risk evaluation of surface subsidence in Datun Coal Mining Area was conducted with Sufer and ArcGIS software, and in the evaluation process, the strong interpolating function of Sufer software and good image processing function of ArcGIS software were brought into full play. With the evaluation results, the breaking grade of brick-stone structural buildings caused by surface subsidence and the breaking area at each grade can be obtained. It pointed out that the breaking of buildings should be treated according to different breaking degrees. Also the over-extraction of underground water should be under control in order to control surface subsidence.
