The monitoring and method of controlled blasting demolition of long span arch bridges

In this paper, the demolition plan of a long span arch bridge is discussed, finite element analysis is done according to the demolition progress, and the monitoring of the blasting demolition is introduced. The demolition plan for long span arch bridges is decided base on the structural property, using the method of from upside to downside to deconstruct the upstructure, and the blasting method to destroy the rib of arch bridge, and the monitoring and safe evaluation of the nearby new bridge is made. This result can be a good case for same project later.
