摘要
本文以2×1000MW大型汽轮发电机基础为研究对象,设计制作了1:10的试验模型。根据目前结构抗震试验方法的特点,采用拟静力试验与拟动力试验相结合的手段,分析了结构在7度多遇地震与罕遇地震作用下的受力特点和破坏过程。试验结果表明,此基础能够达到预期的抗震设防目标,满足规范规定的抗震性能要求。
In this paper, taking a 2x1000MW large turbine-generator pedestal as an example and building a 1：10 scale testing model,pseudo-dynamic and pseudo-static tests have been combined based on the characteristics of currentseismic test methods to analyze structure stress states and aseismic performances under intensity 7 frequently andrarely earthquake. The results indicate that the foundation has preferable seismic capability during the earthquakeand meets seismic design codes requirements.
