Research on deformation velocity in dynamic surface subsidence deformation
(Beijing Campus, China University of Mining and Technology, Beijing 100083, China)
Abstract: The whole process of dynamic surface subsidence deformation was divided into three stages as subsidence development, full subsidence and subsidence attenuation, and a new concept “deformation velocity in surface subsidence” was also put forward. The emphasis was placed on the research on development and variation laws of deformation velocity in surface tilt and horizontal deformation velocity on strike main profile during the stage of dynamic full subsidence. What’s more, the dangerous periods of buildings liable to be damaged were given as well.
Key words: surface subsidence deformation； deformation velocity； surface horizontal deformation
