Open publisher page 0 citations

Abstract

In this paper,the technology of blasting demolition of reinforced concrete girders with super area was discussed.The blasting was performed by adoption of the selected reasonable blasting parameters,detonating network and by considering the relation between the blasting and the slab of the basement,order and blasting parameters as well as the selection of the ignition network.The blasting reached satisfied demolition effect by employing some effective measures,such as covering protection,indirect protection and stress releasing,support replacing.
