The Analysis of the Concrete Lining Damage under Blast Load
Subway is an important part of city traffic system. Once terrorist attack happens in the subway, it might lead to strong response of concrete lining, which seriously threatens the safety of lives and properties. The analysis of the subway concrete lining damage under blast load has become an important question. By the means of finite element software AUTODYN, this essay simulates the highly nonlinear response and dynamic damage of concrete lining when 100kg TNT explodes different altitude above bottom of subway tunnel. It analyses attenuation of pressure and influence on the structure of concrete lining. The damage of concrete lining mainly concentrated in the vicinity of explosion source. Different explosive height will lead to different dynamic damage of concrete lining.
