桥墩扰流对通航净宽尺度影响的试验研究

建桥后由于桥墩扰流,改变了原有的水流条件与河床冲淤条件,从而影响到原有的通航条件。在总结国内主要研究成果的基础上,结合水槽定、动床试验成果,对桥墩扰流宽度影响因素进行深入分析,并用量纲分析法得出其计算公式。

Experimental research on influence of disturbed flow at bridge pier on navigation clearance

Due to the disturbed flow at bridge pier,the original condition of flow and bed scouring and sedimentation was changed,and thus the navigation condition was affected.Basing on a summary of main research achievement in China,and combining the results of static & mobile bed model tests,an in-depth analysis was carried out to the influential factors of disturbed flow′s width,and the calculation formula was obtained by dimensional analysis method.
