| 摘 要： | 采用三维声学多普勒流速仪对弯道内有、无丁坝两种工况下的水流特性进行了系统的试验研究,总结了弯道水流水面横比降、横向环流、流速重分布等特性,重点分析了丁坝对弯道水流流态的影响,进一步证实了丁坝的护岸机理,为相关的工程实践提供理论依据。

| Abstract: | This paper presents an experimental study on the flow characteristics on bend channel flows by means of the advanced three-dimensional acoustics Doppler current meter.The water surface cross circulation and redistribution of velocity in channel bends were summarized;and the effects of spur-dikes on flow state were analyzed.Furthermore,the theory of the protection on bank by spur-dikes was verified.The research result would provide references on other relative projects. |
