摘　　要：对发生较大振动令住户感到不安全的广东省小北江河段蓑衣滩新站房进行了实地测试,通过数据分析,确定了楼房的模态频率和振型,找出了振动的原因是1-3阶模态共振,同时诊断出结构存在损伤,确定了损伤位置,最后提出了减振加固的治理方案。The field measurements are carried out for the Suoyitan new station building that vibrates strongly and results in worry of the residents. After data analysis, the reason why it vibrates strongly is found. That is resonance. The damage location is detected. Finally, the treating scheme of vibration mitigation is proposed.
