摘　　要：为了解趸船工程影响河道行洪的情况,以成都市锦江华阳段的趸船工程为例,对该趸船工程所在河道进行了概化,利用物理模型试验研究了趸船工程对河段水流流态、水位及流速分布的影响。结果表明,该趸船工程虽对局部河段的流态、水位和流速等均产生一定影响,且随来水流量的增加壅水影响范围逐渐加大,但其自身对河道的行洪影响程度,总体上来说较小。In order to realize the impact on river flood under pontoon engineering, combined with pontoon engineering on Huayang Reach of Jiniiang River in Chengdu City, river channel had been generalized to establish a mechanical model of river water, which analyzed the flow pattern, velocity distribution and water level influenced by the barge in the river. The results show that although pontoon engineering had a certain impact on the local water level, flow pattern and veloci ty distribution and the impact would increase with the gradual increasing in the zone of backwater, but its impact on flood is relatively small.
