中文摘要：

为获知CFRP索斜拉桥的动力特性，推动CFRP索斜拉桥在我国的发展并积累经验，对国内首座CFRP索斜拉桥分别进行了基于环境激励和锤击激励的结构动态特性测试研究，对不同测试方案的试验结果进行了对比分析，结果表明脉动测试与锤击激励测试结果在对应的频率值误差小、振型相似；环境激励测试法从测试的可行性、方便性及测试所得频率成分的组成上较锤击激励测试法更为丰富．

英文摘要：

In order to obtain the dynamic properties, for the development of CFRP cable-stayed bridges in China, dynamic tests were carried out with ambient excitation and hammer excitation. Test results obtained under different test conditions are compared and analyzed. It is shown that the corresponding frequency value sees very small difference and vibration modes are similar; the ambient excitation test method is better than hammer excitation test method; with ambient excitation test method, more frequencies can be obtained than the hammer excitation test method.
