摘　　要：我国大城市交通发展方向多为架设高架桥,城市交通已然趋于饱和状态,高架桥施工势必会对原有道路交通影响较大,高架桥施工如何最大程度地减少对城市交通的影响,是我们今后思考的方向。无落地支架作为城市跨线桥盖梁施工的一种常用支撑体系,能充分发挥其力学传导作用,同时也能最大程度地保证下方辅路车辆通行,因其具备施工便捷、成本较低、支撑效果较好、支架拆除便利等优点被广泛使用。Most of the development directions of transportation in large cities in China are erecting viaducts.Urban traffic has already become saturated.The construction of viaducts will inevitably have a greater impact on the original road traffic.How to minimize the impact of viaduct construction on urban traffic is our future thinking direction.As a common support system for the construction of the cover beams of urban cross-line bridges,the no-floor support can fully exert its mechanical transmission function,and at the same time,it can also ensure the traffic of the auxiliary roads below to the greatest extent.It is widely used because of its advantages of convenient construction,low cost,good supporting effect and convenient dismantling of supports.
