【摘要】 利用4-21节点块体单元对哈拉沁水库泄洪洞进水塔进行离散,分析6种工况下进水塔结构的自振特性,并通过反映谱法计算顺水向和垂直水向结构的抗震动力响应,包括结构的动位移和动应力。将动力计算结果与静力计算结果进行叠加,成果显示进水塔的变形和强度均满足要求,为工程设计提供了依据。更多还原

【Abstract】 This paper uses 4-21 node elements to divide the intake tower of flood-releasing tunnel for Halaqin Reservoir and analyzes its self-vibration characteristics under six working conditions.The anti-seismic dynamic responses of the tower along and vertical to the flow direction,including its dynamic displacement and dynamic stresses,are calculated.Finally,by the superposed results of dynamical and static calculation results,it showed that the deformation and strength of the tower all can meet the requirements,which provides the basis for the design of project.更多还原
