Numerical Simulation upon Explosion and Collapse of Viaduct

Abstract:

A rigorous scheme must be formulated in advance before a viaduct is to be exploded, in this case, numerical simulation can provide effective guarantee to the formulation of the scheme. Focusing on the explosion engineering of a large-scale city viaduct, the process of its explosion and collapse were simulated by the LS-DYNA software. The vibration responses of soil surface caused by the explosion and collapse were analyzed, and also the numerical results were compared with the measurement data. The numerical results agreed well with the measurement data, which showed that the simulation method proposed in the paper could simulate the explosion process well and the results could be also an guidline for the similar projections in future.
