采动区框架结构建筑物变形特征分析

Analysis of Building Deformation Characters with Frame Structure of Mining Subsidence Area

为了分析在煤炭开采影响下框架结构建筑变形情况并且与建筑物周围地表变形进行比较,利用三维激光扫描仪在真实坐标系中获取了受到开采影响的安居三中教学楼及其周边地物的点云,提取了建筑物及其周边地表的特征区域数据,分析对比了建筑物及地表的变形特征变化情况。通过与开采沉陷预测软件获得的地表移动变形值进行比对,获取的建筑物与地表变形具有较高的可靠性,具有一定的实用价值。

In order to study buildings deformation with frame structure under coal mining and compared with surface deformation around buildings,point cloud of teaching building of the third middle school and around area that induced by mining were obtained from real coordinate by 3 D laser scanner,so characteristic regional data of buildings and it＇s around was extracted,building and it＇s surface deformation character was compared,contrast to surface movement deformation value that obtained from mining subsidence software,the deformation of building and surface deformation was reliable,and had some practical value.
