Abstract
In this paper the process of ground subsidence is divided into two phases
and an empirical coef-ficient is proposed
on the basis of which the fundamental differential equation of dynamic ground move-ment is modified. The problem is solved that the original time function simulating curve does not agreewell with the actual one. Based on data from observation stations and the modified time function
the pa-per makes foreground processing with visual C++’s object oriented programming
and background pro-cessing with Access database management system. Through communication between the foreground andthe background with MFC ODBC class
dynamic and real time surface movement observation system inClient/Server mode is established. The computational example illustrates that this method can reflect thedynamic characteristics of surface movement
and is of much practical value to mining design and selectionof building precaution measures.
