摘　　要：对广州蓄能水电厂A厂的地下厂房进行振源测试及整体结构环境激励下的模态测试,分析了振源频率成分及来源,模态分析得到厂房结构的多阶模态频率及振型,并与有限元计算结果进行了对比。测试分析结果显示了结构当前振动性能状态,为结构计算模型修正及结构的安全性能评定提供了依据。Vibration source tests and modal tests using ambient excitation of the underground powerhouse of A plant in GPSPS were carried out. The frequency components and sources of vibration were obtained by spectrum analysis. And the modal frequencies and mode shapes of the structure were obtained by modal analysis. The result was compared with that of FEM analysis. The test analysis provides a basis for the structural model updating and structural safety evaluation.
