摘　　要：结合河南省鹤壁市盘石头水库泄洪洞进水塔工程实例,利用大型有限元分析软件ANSYS完成了进水塔实体模型的建立及有限元离散化,对进水塔各工况应力控制关键部位进行了分析。指出高进水塔截面突变处对振型位移有较大影响,在高阶振型的形状特征方面尤为明显,所得结果为工程设计和采取特殊的施工措施提供了可靠的依据。In this paper, a static and dynamic analysis of high intake tower of the flood-discharging tunnel in Panshitou reservoir in Hebi City of Henan Province has been made by using the three-dimension finite element method. The ANSYS is the large finite element software that owns powerful preprocessor and postprocessor function. The intake tower's finite element model has been built and dispersed. It can simulate the true transformation process about the tower's displacement and stress. All kinds of load combinations affect on tower and stress control on key parts of the tower are considered. Expanded sections of the high intake water tower have great effect on the random mode displacement,especially for the form feature of the high order mode. The results supply reliable data and special construction measures for project designers and builders.
