Abstract: This paper gives different numerical analysis results for two kinds of design schemes of the aqueduct across Yellow River obtained by using typical mathematic mechanical models under various structural,loading and combined conditions respectively,such as with or without water in aqueduct,rigid foundation or elastic foundation,etc..The paper also presents the comparative analysis and discussions on dynamic characteristics, dynamic displacements,dymamic stresses of the aqueduct and so on.
