摘　　要：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．The regularity of vortex happening and the methods of eliminating and preventing vortex in two way suction box have been studied in this model test. The factors, which notably influence on the capital investment of pumping station and the performance of pump system, such as bottom floor clearance, box width, etc., also have been tested. The results show that the efficiency of pump system is hardly effected by the variety of suction box size within the normal range.Vortex is the main problem for this kind of suction box.
