首发时间:2008-09-28
摘要:金安桥水电站扩机工程进水塔为大体积的混凝土结构,塔体结构与受力情况均较复 杂。本文采用大型分析软件ansys建模和计算,对进水塔在静、动力状态下其应力和变形的分布规律进行了研究,通过静力计算分析进水塔结构各部位的应力和位移,验证结构的强度要求。通过动力计算确定自振频率,进而分析地震对塔体结构的影响。所得结果为工程的设计和施工提供了可靠的依据。

Static and Dynamic Analysis on Intake Tower of Jin’anqiao Hydropower Station by 3–D Finite Element Method
Abstract:The intake tower of Jin’anqiao Hydropower Station enlargement project is a mass volume concrete structure. The structure and the stress of the tower is complex. In this paper , the finite element method software ANSYS was used for model building and calculation to research the distribute laws of the stress and displacement in state of static and dynamic. In order to validate the strength need of the structure, the stress and displacement of the intake tower was analyzed by static calculation. And the natural frequency was decided by dynamic calculation so that the influence to the tower from earthquake can be analysed. The results may provide credible basis for project designing and construction.
Keywords: Jin’anqiao intake tower finite element static and dynamic analysis
