摘　　要：随着我国经济的快速发展,跨江河的桥梁越来越多,桥梁的兴建使桥墩周围的水流结构发生很大的变化,进而影响河床和桥墩的冲刷。文章以乌龙江大桥为例,采用概化模型试验的方法,研究不同的桥墩抗冲刷防护措施,研究结果表明:采用块石和扭王字块对乌龙江大桥桥墩进行防护,桥墩护墩范围内的河床没有被冲刷,防护效果明显。With the rapid development of Chinese economy, more and more bridges are built across the river.The bridge pier affectsthe surrounding water flow structure, thus affects the river bed and erosion of the pier. Taking Wulong river bridge as an example, different pier protection measuresare analyzed by generalization model tests. The results show that river bed are protected well using block stone and accropodefor bridge piers protection.
