内蒙古 内蒙古科技大学硕士学位论文 III III of these plans require to be exam to sort out which are the best. Take advantage of computer simulating technology, changing the optional parameters such as altering the blasting height from 1.2 meters to 1.6ameters, extending the bomb time of the exploders or cutting down the detonation dose repeatedly, observe and compare the results so as to select the optimal parameters. This is another purpose of this paper. In summary, the simulation results prove that the method combines finite element and software ANSYS/LS-DYNA together to analyze controlled blasting process to the collapse of buildings is feasible, which plays a significant guiding function in the theoretic research on building controlled blasting demolish as well as the demolished designs.
