摘要
本文通过采动过程中地表位移变形的动态分析，建立了下沉盆地形成过程的动态位移变形预计数学模型，分析了它们的变化规律和特点及各参数对地表变形的影响，给出了动态位移变形理论参数的确定方法。实践证明，该方法是“三下”开采预计评价地面保护建筑设施破坏程度的一种有效方法。图４，表１，参３。
Through dynamic andlysing surface movement deformation in mining process,this paper presents a mathmatics model which estimate developing movement deformtion in forming subsidence basin.Analysing its change law, characteristics and parameters affecting surface deformation, a method which calculate the theory parameters of dynamic movement deformation had been given. This method is effective to estimate and evaluate mining under railways,water-bodies, rivers and destorying degree of surface prateating buildings and installations. 4figs.,1tab.,3refs.
