摘要
文中将地表动态沉陷变形发展变化的全过程划分为下沉发展、充分下沉和下沉衰减三个阶 段，分别分析了这三个阶段地表沉陷变形的发展变化规律。
In the paper, the whole process of dynamic surface subsidence deformation is divided into such three stages as subsidence development, full subsidence and subsidence attenuation, and corresponding development and variation laws of surface subsidence deformation in these three stages are also respectively analyzed.
