摘要
高地震烈度、高水头作用下的电站进水塔结构稳定性一直是水电设计者及工程界研究人员密切关注的重大问题。结合具体工程实例,采用大型有限元计算软件ANSYS建模和分析计算,对古水水电站进水塔在静、动力荷载组合作用下塔体的应力及变形的分布规律进行分析研究。通过对进水塔结构各部位的应力及位移等计算结果的分析,论证塔体的结构稳定性及安全性,并对古水水电站进水塔的结构的设计给出合理性建议。
The designers and hydropower engineering researchers are still focus on the important question that the structure of stability of intake tower for the hydropower station which is under the action of high earthquake intensity and high water head,this article which is combining with specific engineering example and use ANSYS that is the large- scale finite element calculation software to modeling and calculation. We can analysis and research the distribution regular of stress and deformation about the tower body of the intake tower of the Gu Shui hydropower station by using ANSYS.Through analysis the calculation result of the stress and displacement about the each part of the structure of the intake tower,we can ensure that the structure of tower body is safety and rational. Besides,rational suggestion can be put about the intake structure of the Gu Shui hydropower station.
