COMPUTATION OF CHARGING CAPACITY FOR BOREHOLE IN DEMOLITION BLASTING OF REINFORCED CONCRETE STRUCTURE |
| |
| Abstract: | On the basis of analysis of splitting forms of reinforced concrete, considering the conditions of compounded reinforcing bar, such as the strength; net standard; layers and so on, the influence on demolition blasting is handled by way of data processing, and a formula, that is tested and verified in practical engineering for computing the charging capacity of borehole in intensified tossing blasting of reinforced concrete, is put forward. |
