通过模型试验研究了箱涵式双向进水流道内的涡带发生规律及有效的消涡防涡措施，并对影响工程投资及装置性能的主要尺寸如悬空高、流道宽度及吸水喇叭管进行了试验研究． 结果表明：流道尺寸在常规取值范围内对装置效率的影响较小，而这类流道的主要问题是其内部的涡带．
Through the model test, the law of the vortex band in the box culvert two-way inlet channel and the effective measures of vortex shedding and vortex prevention are studied. The main dimensions that affect the project investment and device performance, such as the high dwell height, the width of the runner and the water pipe Experimental Research. The results show that the runner size has less influence on the device efficiency in the range of normal values, and the main problem of such runners is its internal vortex band.
