| 摘 要： | 通过对邢台矿区铁路下开采的地表沉陷进行数值模拟分析的方法研究了采空区引起的地表变形特征，论证了地表变形规律，得出矿区铁路下开采地表沉陷主要分三个阶段，即下沉发展阶段、下沉充分阶段和下沉衰减阶段，这为进行该采空区地表沉陷处理奠定了理论基础。

| Abstract: | With the Xingtai mining area as a practical example,the characteristics of the ground deformation in the goaf under the railway are analysed by means of numerical simulation and analysis in the paper,with the ground deformation law verified.It is concluded that the ground settlement mostly undergoes three phases,namely,the subsidence developing phase,subsidence plenitude phase and subsidence declining phase.Therefore,the paper may serve as a theoretical basis for tackling ground settlement. |
