摘　　要：某体育中心游泳馆跳台采用混凝土悬臂结构,体育馆完工后使用过程中,运动员反映出现共振感觉。通过对跳台现场实测和模态参数计算分析可知,跳台悬挑混凝土板的测试基频约是7Hz^14Hz,塔柱的基频率约是3Hz,塔柱基频过低是产生振动的主要原因。本工程案例对同类型跳台振动影响检测及分析处理有借鉴意义。The platform of a Sports Center Natatorium is concrete cantilever structure,after the completion of the the stadium,the athletes reflect the feeling of resonance a when they are training on the platform. Through the analysis of field test and fundamental mode calculation,test frequency rate of the platform is about 7 - 14 Hz,the tower frequency is about 3 Hz,the low frequency vibration of tower is the main reason. The case of this project has a reference to the test and analysis of the vibration of the same type platform.
