【Abstract】 It is analysed of the surface movement resulting from engineering excavation, such as underground mines, open-pit mining, railway, highway, foundation pit, tunnel and underground engineering, and its deformation’s characteristics. Surface buildings can be allowed to very slightly settle and deform, except affecting their normal use and their damage. The deformation rules are understood by prediction of surface movement and deformation survey of surface and its nearby buildings to take precautions against disasters resulting from engineering excavation.更多还原
