水工建筑物多以混凝土结构组成,而这些混凝土结构多处在气候恶劣的环境中,受泥沙、水流、物理、化学、气温等因素影响颇多。混凝土的破坏冻融破坏为常见,致使许多水工建筑物的运行寿命大为缩短,造成极大浪费。所以有必要进一步探讨水工建筑物混凝土的冻融破坏机理及防治措施。
Hydraulic structures are mostly composed of concrete structures, which are heavily influenced by sediment, water flow, physical, chemical, temperature and other factors in many places with harsh climatic conditions. Concrete damage freeze-thaw damage is common, resulting in many hydraulic structures greatly reduce the operational life expectancy, resulting in tremendous waste. Therefore, it is necessary to further investigate the mechanism of freeze-thaw damage of hydraulic structures and their prevention measures.
