【摘要】 结合黑河引水工程引水洞放水塔的三维拟静力有限元分析，给出了附属结构或质量在地震荷载作用下的等效结点荷载确定方法，得到了各种荷载工况下，塔体的位移、应力、内力成果，为塔体的安全设计提供了重要参考依据。更多还原

【Abstract】 In combination with the 3D quasi static FEM analysis for intake tower of delivery tunnel of Heihe water diversion project, the paper offers the method of equivalent load for joints considering appurtenant structure or mass under seismic load, by which the displacement, stress and internal force are obtained. The results provide reference for the safety design of the tower.更多还原
