摘　　要：建立了弯道水流概化模型试验,利用ADV对三维流速数据进行了采集。通过对弯道水流流速的分析统计,对弯道环流沿程变化和分层结构进行了初步研究。结果表明,环流结构在弯顶前后呈现出不同规律,并且存在沿水深上下分层的现象。研究为进一步深入探讨弯道水流特性奠定了基础。Based on the generalized curved conduit flow experiment, adopting the analyze the 3D velocity data, the circulation configuration in curved conduit are studied, the that the circulation configuration is different before and after the bend apex and may stratify has laid a basis for further exploration of flow characteristics of the curved reach. ADV to measure and results of which show in depth. The research .
