利用氢气泡技术在室内测量了桥台局部冲刷的三维流场。结果表明：该构造以大的初涡及其伴生的下流为主，且主要局限于原层位以下的冲刷孔内。本文的价值还在于收集了大量的数据，为今后桥台流动和冲刷数值模型的开发和标定提供了有益的参考。
The three dimensional flow field for local scour at bridge abutments was measured in the laboratory using the hydrogen bubble technique. The results show that the flow structures are dominated by a large primary vortex and its associated downflow and that they are confined predominantly within the scour hole beneath the original bed level. The value of this paper is also in the large amount of data collected, which would be useful for the future development and calibration of numerical models of flow and scour at bridge abutments.
