摘　　要：以南平市某大厦为例,通过采用环境振动法对建筑进行结构动力测试,从中提取结构的模态参数,为建筑的健康诊断提供依据,并将测试结果与经验值进行了比较,分析了存在偏差的可能影响因素,为今后类似检测提供借鉴依据。Take a building in Nanping as an example, the ambient vibration was carried out in structure dynamic test of building to acquire the modal parameters, which can provide the basis for health diagnosis of building. The test results were compared with the empirical values to analy-sis of influencing factors of deviation. It can be a conference for follow-up structure dynamic test in health inspection of high-rise building.
