Abstract
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...
