摘　　要：对南水北调穿黄渡槽的两种设计方案分别选择了典型的数学力学模型,对槽内有水、无水,刚性地基,桩土相结合的弹性地基,冲刷与不冲刷,横槽向、顺槽向及竖直向地震等不同的荷载作用工况及其组合工况进行了抗震计算,井对渡槽的地震动态特性、动位移、动应力等进行了比较分析和讨论。This paper gives different numerical analysis results for two kinds of design schemes of the aqueductacross Yellow River obtained by using typical mathematic mechanical models under various structural, loadingand combined conditions respectively, such as with or without water in aqueduct, rigid foundation or elastic foun-dation, etc.. The paper also presents the comparative analysis and discussions on dynamic characteristics, dynam-ic displacements, dyffiamic stresses of the aqueduct and so on.
