| 摘 要： | 介绍了利用三维结构模型对某一正在设计中的贯流式机组水电站厂房整体结构的自振特性,用激光全息干涉测振技术进行了模型试验,并用动力有限元法计算其整体结构的自振特性和在地震作用下的动力反应特性。通过上述研究,得到了目前采用平面模型分析所不可能得到的许多新的认识,可作为整体厂房结构抗震设计的参考。

| Abstract: | On a three-dimensional structural model, this paper presents the test of the natural vibration characteristics of the whole structure of a hydroelectric plant with through-flow turbine by laser holographic interferometry. The dynamic finite element method was applied to analyse the natural vibration characteristics of that plant. Based on above results much information is obtained, which cannot be obtained by plane structural model analysis. The results can be used as reference for earthquake-resistance dynamic design. |
