Abstract:In order to reveal the influence law of explosion load when new subway under-crossing existing subway, the research with the method of combining theoretical calculation and numerical simulation was developed. With theoretical calculation method, the reasonable structural parameters and material parameters were chose, then the equivalent static load of under-crossing structure was obtained at the condition of explosion wave. By using the ANASYS/LS-DYNA software, the propagation law of explosion wave and the loa… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
