Horizontal drawing cable bridge with hollowed-out bridge deck slabs
The horizontal drawing cable bridge comprises a plurality of steel cables which are arranged in the same direction and tensioned, the bridge deck is laid on the steel cables, and hollow holes allowing air flow to vertically penetrate through are formed in the bridge deck. By laying the bridge deck with the hollow holes on the steel cables, airflow above and below the bridge deck can be communicated, so that the streaming form around the bridge is effectively changed, the pressure difference between the upper surface and the lower surface of the bridge is reduced, and the purpose of improving the pneumatic stability of the bridge can be achieved.
本发明公开了一种具有镂空桥面板的平拉索桥，包括若干道同向排布且张紧的钢缆，钢缆上平铺有桥面板，桥面板上成型有能够使风流竖向穿过的镂空孔洞。通过在钢缆上铺设具有镂空孔洞的桥面板，使得桥面上下的气流能够互通，从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，进而能够达到提高桥梁气动稳定性的目的。
