Cylindrical Buildings Blasting Demolition Expert System Development And Its Application

The numerical simulation of blasting demolition is onc of the advancing front problems that many scholars are discussing. In this paper, with the theoretical knowledge of blasting demolition, building structure, material mecharics etc, we set up all kinds of knowledge base, such as blasting powder, explosive properties of blasting powder, spatial distribution of cylindrical building, mechanical properties of building materials. With the actual projects and the field experience, we set up all kinds of sample base, for example, engineering condition, detonation parameter, blasting effect. In accordance with the principles and methods of expert system, we come into being some inference mechanism, optimize the mode of blasting, detonation parameter etc, and predict blasting effect. Taking advantage of Delphi powerful function, we develop a interactive graphics and data processing system, develop some analysis tools, carry out the flexible output of the result of expert system.. It is successful applied in the project that demolish two chimneys of ZhanYi Glasswork by blasting procedure.
