| 摘 要： | 文章借助弹性薄板理论,建立地表沉陷变形的预计模型,并给出任意点地表变形的预计表达式。针对地下开挖空间形状的不规则性,推导出了水平空间、倾斜面空间以及不规则开挖空间：椭圆抛物面空间、二次柱面空间以及二次曲面空间地表沉陷的预计公式。本文的研究结果对该类开采沉陷问题的研究具有一定指导意义。

| Abstract: | The prediction model of surface subsidence deformation is built up by elastic plate theory.Also the formula of surface deformation at random point is given.Considering the irregularity of the underground excavating space,the prediction formulas for surface subsidence are derived,including the formula of level space,tilt space and the irregular excavation space,and the last covers elliptic paraboloid space,the second cylindrical space,and quadric space.The results have guiding significance to the research of such mining subsidence problems. |
