深部老采区残余沉降预计方法及其应用

废弃老采空区上方地表残余沉降预测是新建建筑物抗变形结构设计的基本依据。根据长壁老采空区破裂岩体结构特点和活化机理，深部长壁老采空区的活化沉降特征主要表现为残留空隙的再压密，地表残余沉降呈现中部大、边缘小的似盆形连接分布特点。在此基础上，建立了深部长壁采空区上方地表残余沉降预测的随机介质模型。结合在长壁老采空区上方建设的徐州某工业园工程实例，对厂区地表残余沉降和变形分布进行了预测，预测结果已成为各类建筑物抗变形结构设计的基本依据。

Study on the Prediction Method of Ground Residual Subsidence in the Deep Abandoned Longwall goal and its Applicatic

The prediction of ground residual subsidence is the basis of anti-deformation structure design for newly-built construction over abandoned golfs. On the basis of structural characteristic and activation mechanism of fractured rock in and over golfs, the active subsidence feature of deep abandoned lingual golfs is mainly featured with re-compaction of residual intersperse. The ground residual subsidence takes on a basin-shaped continuous distribution with a characteristic of larger in the midst and smaller around. Base on these features, the random medium model of ground residual subsidence prediction over lingual golfs is established. Combined with the Xuzhou industrial area constructing over abandoned lingual golfs, the residual subsidence prediction has been carried out and the predictive results have been applied to design anti-deformation constructors for various industrial buildings.
