| 摘 要： | 通过武汉天兴洲公铁两用桥2^#浮运围堰下沉模拟试验，分析了在浮运围堰下沉期间不同阶段围堰周围水流流速、紊动强度及河床局部冲淤情况．针对浮运围堰下沉期间的水流及河床地形等条件，对浮运围堰下沉时河床局部冲刷深度进行了预测，试验预测结果与实测资料较为吻合． |

| Abstract: | Based on the sinking simulation test for No. 2 floating cofferdam of Wuhan Tianxingzhou Rail-Cum-Road Bridge, the flow velocity, turbulence intensity and local scour around the floating cofferdam at different sinking phases are analyzed. According to the flow and riverbed conditions during the sinking process ot the tloating cofferdam, the local scour depth is predicted, and the predicted results are in good agreement with the field data. test |
| Keywords: | floating cofferdam flume test flow structure local scour prediction |
