STUDY ON TIME FUNCTION OF SURFACE SUBSIDENCE
—— THE IMPROVED KNOTHE TIME FUNCTION |
|
|
|
|
Abstract The Knothe time function was known to be able to describe the whole process of surface subsidence. Through theory proof and comparison with actual measurement data，the fault of Knothe differential equation is discovered in describing the whole process of surface subsidence. By means of analyzing the whole process of surface subsidence，a more objective and reasonable expression for time function of surface subsidence is derived and presented，which has been verified with actual measurement data of Dongpang mine.
