Abstract

The invention discloses a bridge wind wave and flow coupling field, an elastic model and a dynamic response experiment test system body. The system comprises a wind wave and flow coupling field simulation system, a bridge elastic model in the wind wave and flow coupling field and a dynamic response experiment test system body. The wind wave and flow coupling field is generated by the wind wave and flow coupling field simulation system with time synchronization and space correlation of wind, wave and flow considered; simulation of the characteristic of a bridge elastic structure is achieved by the bridge elastic model in the wind wave and flow coupling field in the wind and flow coupling field generated by the wind wave and flow coupling field simulation system; the dynamic response of the bridge elastic model is tested by the dynamic response experiment test system body, and a test result is obtained. By means of the bridge wind wave and flow coupling field, the elastic model and the dynamic response experiment test system body, simulation of the wind wave and flow coupling field and the bridge elastic model in the wind flow coupling field and the dynamic response experiment test body can be achieved.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a bridge wind-wave-current coupling field, elastic model simulation and dynamic response test system. Background technique [0002] After entering the 21st century, my country has entered a new era of sea-crossing bridge construction, and has successively built sea-crossing bridges such as the East China Sea Bridge, the Hangzhou Bay Bridge, and the Qingdao Bay Bridge. At present, the Xiangshan Port Cross-sea Bridge, the Hong Kong-Zhuhai-Macao Sea-cross Bridge, and the Quanzhou Bay Cross-sea Bridge are under construction. In addition, a number of giant bridge projects outside the sea are under planning and construction, such as the Qiongzhou Strait Bridge and the Bohai Strait Bridge. For sea-crossing bridges, strong winds, waves and currents are important factors controlling bridge construction. [0003] In the marine environment, the wind wave current field is not a ...
