| 摘 要： | 将地表动态沉陷变形发展变化的全过程划分为下沉发展、下沉充分和下沉衰减3个阶段，分析了这3个阶段地表沉陷变形的发展变化规律，提出了地表沉陷变形速度的新概念，研究了地表下沉过程中的地表倾斜变形速度和水平变形速度的发展变化规律，给出了建筑物易受损坏的危险期，水平拉伸（或压缩）变形速度量大于拉伸（或压缩）变形值最大阶段.

| Abstract: | The whole process of dynamic surface subsidence deformation was divided into such three stages as subsidence development,full subsidence and subsidence attenuation.The development and variation laws of surface subsidence deformation in these three stages were respectively analyzed,and a new concept"deformation velocity in surface subsidence" was also put forward.What's more,a research was made on development and variation laws of deformation velocity in surface tilt and horizontal deformation velocity in the process of surface subsidence,and dangerous periods of buildings liable to be damaged were given as well,it is the stage from max.deformation velocity of horizon stretch(or compression)to max.stretch(or compression)deformation value. |

| Keywords: | dynamic surface subsidence deformation surface deformation velocity subsidence stage |
