英文摘要	Dynamic test of double curved arch bridge based on environmental incentives. And Peak value method stochastic subspace identification method is used for modal analysis, and bridge modal parameters are obtained. The results were compared with the finite element software Midas civil, and results are consistent. The test shows that the bridge modal parameters can be identified in the environmental stimulus response. Measured frequency is lower than the finite element calculation of frequency; it means the bridge stiffness is lower. The identified dynamic properties can be served as the basis in the finite element model updating, damage detection, condition assessment and health monitoring of the bridge.
