摘　　要：随着我国大量大中型灌区工程的实施,工程中存在各种渠系建筑物,其中渡槽工程数量较多,总工程量较大。选择亭子口灌区工程第五流量段为代表,从水力条件、结构及力学条件、施工工艺和工程投资等方面对矩形和U形2种不同的槽身断面型式进行对比分析。结果表明:对于流量较大的总干渠渡槽槽身结构断面,槽身结构采用U形断面水力学条件更好、施工工艺更简单、投资更省。With the implementation of numerous large and medium-sized irrigation projects across China,various canal system structures have been constructed,among which aqueducts are particularly numerous and involve substantial engineering efforts.This study selects the fifth flow section of the Tingzikou Irrigation Project as a representative case and conducts a comparative analysis of rectangular and U-shaped aqueduct cross-sections.The analysis considers hydraulic conditions,structural and mechanical requirements,construction techniques,and project investment.The results indicate that for main canal aqueducts with large flow rates,U-shaped cross-sections offer superior hydraulic performance,simpler construction processes,and lower investment costs compared to rectangular cross-sections.
