鹦鹉洲大桥对航道整治工程的影响及解决措施

摘要

In order to investigate the relationship between the Yingwuzhou bridge and waterway regulation projects,the variation of erosion and deposition of the riverbed,the range of local scour hole and the result of protection schemes were analyzed by the combination of the fixed bed and movable-bed model tests in this paper. The result shows that the local scouring around pier will affect the stability of waterway regulation projects.So it is necessary to take some protection projects.Through the implementation of the protection projects,the construction of the bridge will have no adverse effect on waterway regulation works.%为研究解决鹦鹅洲大桥对航道整治工程的影响问题,通过整体模型与局部模型试验相结合的手段,对建桥前后桥区河段局部河床冲淤变化情况、局部防护范围及防护措施效果进行了研究.试验结果证明,桥墩局部冲刷会对航道整治工程的稳定性产生影响,因此必须研究并采取防护措施.通过防护方案的实施,大桥建设不会对航道整治工程效果造成明显不利影响.
