| Abstract: | In this paper,based on the theory of dynamic and stable mechanics,principle of action for bear-
ing body of falling chimney in the process of blasting and demolition is analyzed, combining some engineer
ing examples, the effective length of bearing body of blasted chimney and itS influence to chimney falling di-
rection are expounded. and some measures to avoid falling in wrong direction and assure construction safety
are given. |
