Wind-resistant guardrail of large-span bridge
The invention provides a wind-resistant guardrail of a large-span bridge. The wind-resistant guardrail of the large-span bridge comprises overhaul handrails arranged on the two sides of a bridge floorand roadway guardrails arranged on the two sides of a roadway of the bridge floor. The overhaul handrail comprises first through areas and first closed areas which are alternately arranged in the bridge direction, the roadway guardrail comprises second through areas and second closed areas which are alternately arranged in the bridge direction, and the first closed areas and the second closed areas on the same side of the bridge floor are arranged in a staggered mode. The outline structures of the overhaul handrail and the roadway guardrail on the bridge are processed to form a semi-closed and semi-transparent structural form, and the closed areas of the overhaul handrail and the roadway guardrail are arranged in a staggered manner, so that the streaming form of airflow around the bridgestructure is effectively changed, and the purpose of inhibiting vortex-induced vibration of the bridge is achieved.
本发明提供了一种大跨度桥梁的抗风护栏，包括设置在桥面两侧的检修栏杆，以及设置在桥面的车行道两侧的车行道护栏；所述检修栏杆包括沿顺桥向交替布置的第一通透区和第一封闭区，所述车行道护栏包括沿顺桥向交替布置的第二通透区和第二封闭区，且桥面同侧的第一封闭区和第二封闭区错列布置。该发明通过对桥梁上检修栏杆和车行道栏杆的外形结构进行处理，使其形成半封闭半通透，且检修栏杆和车行道栏杆的封闭区错列布置的结构形式，有效改变了桥梁结构周围气流的绕流形态，从而达到了抑制桥梁的涡激振动的目的。
