本文简要介绍通过模型试验和动力分析对坝内式厂房段的动力特性和地震反应进行研究的部分成果. 在可以模拟实际地震波的电磁振动台上进行了模型试验,用于空间反迭代法和振型叠加方法作了二维动力反应分析计算.试验和计算的结果比较一致. 研究表明:坝内式厂房段的动力特性和地震反应与其他坝段并无显著不同.
In this paper, some results of studying the dynamic characteristics and seismic response of dam-in-house sections are briefly introduced through model tests and dynamic analysis.Models are tested on electromagnetic vibrating table that can simulate real seismic waves, which are used in space inverse iterative method and vibration analysis Type superposition method is used to do two-dimensional dynamic response analysis and calculation.The results of the experiment and calculation are consistent.The research shows that the dynamic characteristics and seismic response of the dam-in-house section are not significantly different from other dam sections.
