The development and application of dynamic parameter database of rock-mechanics based GIS

Abstract

The mechanical properties of rocks can be continuously calculated with the help of theory of elastic mechanics and logging data (AC-sonic log, DEN-density log, CNneutron log). A GIS administration system will be very helpful in running these data. This system applies the client/middle tier/server framework. It is composed of database, data access engine, purview control middleware and clients. Drawing layers are the basic spatial data unit. The 3D distribution of mechanical properties of rocks can be achieved underground by GIS visualization modules.
