摘　　要：渡槽因常年通水可能引发混凝土结构内部钢筋锈蚀膨胀导致混凝土结构裂缝,也可能因常年经受冻融循环产生温度应力而引起裂缝。为此,文中主要通过对渡槽槽身外观质量、混凝土抗压强度、碳化深度、槽身裂缝等方面的调查试验来分析研究渡槽槽身产生裂缝的主要原因,为水利运管单位运行维护提供理论支撑。The constant water flow of aqueduct may lead to the corrosion and expansion of steel bars inside the concrete structure,which may also cause cracks due to the temperature stress generated by the freeze-thaw cycle.To this end,the paper mainly analyzes the main reasons for the formation of cracks in the aqueduct through the investigation and test on the appearance quality of the aqueduct body,concrete compressive strength,carbonization depth,and cracks in the aqueduct body,so as to provide theoretical support for the operation and maintenance of water transport and management units.
