摘　　要：我国自20世纪50年代以来，修建了许多小、中、大型的钢筋混凝土渡槽，有的渡槽损坏严重，有的处于带病运营的状态，出现了一些老化的病害，如槽身裂缝、混凝土剥落、渗漏、基础沉降现象等，严重影响了混凝土渡槽的进一步建设和发展。因此，研究已建渡槽发生老化病害的机理和原因是十分有必要的。本文以20世纪70年代初期修建的老林河渡槽为研究对象，分析了渡槽老化病害的原因，并提出了一些有益的建议。Aqueduct is one of the most widely used in the project of water conveyance and water diversion. Since the second half of the twentieth century, many small, medium and large reinforced concrete aqueducts have been built, while some of them had serious damages, and others are operated with defects. There have been some aging defects, such as cracks of groove bodies, concrete spalling, leakage, foundation settlement, etc. These have seriously affected the further development and construction of concrete aqueducts. Therefore, research on the mechanism and cause of defects of the built aqueduct aging is very necessary. This thesis takes the Laolin River Aqueduct built in the early 70s as the research object to analyze the causes of aging defects of the aqueduct, and puts forward some suggestions.
