Method and device for analyzing driving stability of bridge deck

The invention provides a method for analyzing the driving stability of a bridge deck in a wind environment. The method comprises the steps of: modeling a preset bridge, and determining a model bridge;carrying out a wind tunnel test on the model bridge, measuring the wind speeds of all lanes on the bridge deck at different heights by arranging sensors, and calculating an equivalent wind speed Ue;and introducing two concepts of a wind speed reduction coefficient lambda and a moment reduction coefficient gamma to represent the weakening effect of a bridge structure on lateral wind. On the basisof a wind tunnel experiment on the model bridge, the wind speed reduction coefficient and the moment reduction coefficient are introduced, and a calculation formula of a driving roll and sideslip critical wind speed based on the above-mentioned parameters is deduced; and an evaluation method for driving stability is given in combination with specification and related regulations, and the drivingsafety is improved. 本发明提供了一种
