The paper presents the design of bridge blasting demolition scheme. methods has become preferred method for not only in war period but also where service life is exceeded. Compared with other method, evince more advantages as higher demolishing progress, lower cost and easier construction safety control. scheme contents position, parameters protections.

Blasting demolition plays an important role in building demolition, and numerical-simulation methods can facilitate the optimization of blasting-demolition schemes. To study influence delay-time differences between columns on blasting effect small-aspect-ratio reinforced concrete structures, a separated common node model structures was established through finite element numerical simulation sof...
