Design contents and methods of bridge blasting demolition scheme

When the service life of bridge structure ends, it must be removed. Blasting demolition method is a common method in bridge demolition engineering, and a reasonable blasting plan is essential to safely achieve the goal of bridge blasting demolition. By summarizing and analyzing related research results and engineering practice experience, the design content and method of bridge blasting demolition scheme were studied. The design content of bridge blasting demolition scheme mainly includes blasting position design, network design, parameter design and safety protection design. In practical operation, some design work can be carried out by referring to simple theory, while some design work needs to be carried out by referring to relevant engineering experience.
