Abstract

The invention discloses a bridge type wind measurement system which comprises a connecting cable and a power supply assembly. The two ends of the connecting cable are connected to the two ends of a preset bridge respectively, at least one observation platform is arranged on the connecting cable, and a wind observation part is arranged on the observation platform and used for measuring high-frequency three-dimensional wind data, collecting the high-frequency three-dimensional wind data and outputting the high-frequency three-dimensional wind data. The power supply assembly is electrically connected with the wind observation part. According to the embodiment, the observation part is directly installed at the real position of the preset bridge deck through the connecting cable and the observation platform, and then the three-dimensional turbulent flow fluctuating wind speed is directly observed, so that high-frequency three-dimensional wind at the real positions of the bridge decks on canyons, valleys and rivers can be measured before the bridge is built; accurate and reliable three-dimensional wind observation data are provided for bridge wind resistance design, and the data is used for calculating bridge wind engineering parameters.

Description

technical field [0001] The invention belongs to the field of wind observation, in particular to a bridge-type wind measurement system. Background technique [0002] Wind resistance is an important factor to consider in bridge design. The wind resistance design of bridges requires obtaining wind engineering parameters, such as maximum wind speed, wind angle of attack, wind deflection angle, etc. Theoretically, it is necessary to measure the wind at the bridge construction location, that is, the real position of the bridge deck, and use high-frequency three-dimensional wind observation instruments to obtain high-frequency three-dimensional wind data, so as to accurately calculate the wind engineering parameters required for the wind resistance design of the bridge. However, in actual observation, the observation instrument cannot be installed on the bridge deck before the bridge is erected, and the instrument can only be installed at a place close to the actual construction p...
