摘　　要：南水北调东线山东段济平干渠工程由于施工条件和建成后的服役条件复杂,渠道衬砌混凝土耐久性要求高。针对济平干渠衬砌混凝耐久性要求的抗渗、抗冻、抗裂等关键特性进行了试验研究,进而从环境条件、施工工艺、混凝土配合比角度提出提高渠道衬砌混凝土耐久性的措施,为后续工程积累经验。Shandong section Jiping canal is the project of South-to-North Water Transfer east route, as it has complex conditions of construction and operation after completion, and higher requirement for the lining concrete durability of canal.The key characteristics, which are anti-permeability, anti-freezing and anti-crack of lining concrete durability requirements for Jiping canal, are tested and researchd.A measure for improving canal lining concrete durability is proposed, from the angles of environment condition, construction technology and concrete mix proportion, and accumulating experiences for subsequent project.
