Horizontal drawing cable bridge with bridge deck slab mechanism with high wind-resistant stability
The invention discloses a horizontal drawing cable bridge with a bridge deck slab mechanism with high wind-resistant stability, which comprises a plurality of steel cables extending along the longitudinal bridge direction, a plurality of cross beams are distributed on the steel cables along the longitudinal bridge direction, a plurality of bridge deck slabs are laid on the cross beams, and the bridge deck slabs can turn over to form channels for air flow to vertically pass through. By arranging the bridge deck slab capable of being overturned, when the horizontal drawing cable bridge encounters strong wind, the bridge deck slab can be overturned under the action of airflow to form a channel allowing the airflow to vertically penetrate through, so that the airflow above and below the bridge deck can be communicated, the streaming form around the bridge is effectively changed, and the pressure difference between the upper surface and the lower surface of the bridge is reduced; the pneumatic stability of the bridge can be improved.
本发明公开了一种具有高抗风稳定性桥面板机构的平拉索桥，包括若干道沿纵桥向延伸的钢缆，钢缆上沿纵桥向分布有若干横梁，横梁上铺设有若干桥面板，桥面板能够翻转从而形成供气流竖向穿过的通道。通过设置能够翻转的桥面板，使得当平拉索桥遭遇强风时，桥面板可以在气流的作用下翻转形成供气流竖向穿过的通道，从而使得桥面上下的气流能够互通，进而有效地改变了桥梁周围的绕流形态、降低了桥梁上下表面压差，能够达到提高桥梁气动稳定性的目的。
