Abstract

Wind barriers are commonly adopted to prevent the effects of wind on high-speed railway trains, but their wind-proofing effects are greatly affected by substructures. To investigate the effects of wind barriers on the aerodynamic characteristic of road-rail same-story truss bridge-train systems, wind tunnel experiments were carried out using a 1: 50 scale model. Taking a wind barrier with a porosity of 30% as an example, the aerodynamic characteristics of the bridge-train system under different wind barrier layouts (single-sided and double-sided), positions (inside and outside) and heights (2.5 m, 3.0 m, 3.5 m and 4.0 m) were tested. The results indicate that the downstream inside wind barrier has almost no effect on the aerodynamic characteristics of the train-bridge system, but the downstream outside wind barrier increases the drag coefficient of the bridge and reduces both the lift coefficient and drag coefficient of the train due to its effect on the train’s wind pressure distribution, especially on the train’s leeward surface. When the wind barriers are arranged on the outside, their effects on the drag coefficient of the bridge and shielding effect on the train are greater than when they are arranged on the inside. As the height of the wind barrier increases, the drag coefficient of the bridge also gradually increases, and the lift coefficient and drag coefficient of the train gradually decrease, but the degree of variation of the aerodynamic coefficient with the height is slightly different due to the different wind barrier layouts. When 3.0 m high double-sided wind barriers are arranged on the outside of the truss bridge, the drag coefficient of the bridge only increases by 12%, while the drag coefficient of the train decreases by 55%.

摘要

公铁同层桁架桥内的列车所处风环境复杂, 随着公铁同层桥梁桥面越来越宽, 侧风作用下列车 的安全问题越来越突出。 为研究风屏障对公铁同层桁架桥-列车系统气动特性影响, 对某大跨度公铁同 层桁架悬索桥进行节段模型风洞试验, 以30% 透风率风屏障为例, 测试了不同风屏障布置形式(单、双 侧)、布置位置(内、外侧)和4 种高度(2.5 m、3.0 m、3.5 m 和4.0 m)条件下车桥系统气动特性。 结果表 明: 下游内侧风屏障对车桥系统气动特性几乎无影响, 但下游外侧风屏障会增大主梁阻力系数, 同时 减小列车升阻力系数, 影响列车背风面负压区甚至列车其余各面风压; 风屏障布置在外侧时对主梁阻 力系数的影响大于风屏障布置在内侧时, 对列车的遮挡效果也优于风屏障布置在内侧时; 随着风屏障 高度增加, 主梁阻力系数逐渐增大, 列车升阻力系数逐渐减小, 但车桥气动力系数随风屏障的变化程 度会因风屏障布置位置不同而略有不同; 在该桁架桥外侧布置3.0 m 高双侧风屏障时, 主梁阻力系数 仅增大12%, 而列车阻力系数最大减小55%, 风屏障防风效果较好。
