The studying of the different sections deck shows: the variation pattern of flutter critical wind speed of bridge with flat box deck and wind yaw Angle is significantly affected by wind attack Angle.
研究发现：扁平箱形断面桥梁的颤振临界风速与风偏角的关系明显地受到风攻角的影响。

As the three-dimensional flutter theory is still not satisfactory at present, it seems necessary to have a full-model wind tunnel test for such a type of bridge.
斜张桥的三维颤振理论目前尚不成熟，有必要进行这种桥型的全模型风洞试验。

The flutter stability of suspension bridge is becoming more and more important with increase of the span.
