Dynamics Analysis on Blasting Demolition of a Special Framework Buiding
It is difficult to control the blasting slanting direction and slanting center of the anamorphic framework building with the conventional methods. There are few such examples in practice and few blasting technology analysis in theory. In this essay, the blasting of RC framework, whose horizontal projection is right-angled triangle, is taken for example and calculated and analyzed. With the complicated conditions, 3 meters far from the protected building, different blasting projects are analyzed with the help of the software of structure analysis to ensure the sufficiency of blasting disassembly, the planned slanting direction and the security of the protected object. It is found out that the sequence of the rupture of pillar is accordance with the blasting sequence . The calculation of anti-pressure, anti-pull and anti-snip of pillar and girder in different projects has been processed. After calculation, analysis, contrast, the following parameters are fixed, such as the blasting sequence, the parameters of blasting cut and the number of blasting pillar, to ensure the expected design. In practical blasting, the slanting direction and the scope of blasting are completely in accordance with the previous design. Such practice provides valuable methods and experience for the similar engineer blasting.
