摘要
为揭示既有水工结构在典型河湖调蓄环境下的耐久性退化模式,基于刘老涧新闸5个关键区段开展现场取样,系统检测其抗压强度、碳化深度、氯离子扩散系数、孔结构、抗渗与抗冻性能等指标,对结构建成多年后的材料状态进行全面评估。相关研究成果不仅明确了老旧水工建筑在复杂水文气候背景下的关键退化机制,也为类似水闸和河湖调控建筑的耐久性评估、运行维护与加固设计提供了工程依据。
To reveal the durability degradation mode of existing hydraulic structures in typical river and lake regulation and storage environments,on-site sampling was carried out at five key sections of the Liulaojian New Sluice.Indicators including compressive strength,carbonation depth,chloride ion diffusion coefficient,pore structure,impermeability,and frost resistance were systematically tested,and the material state of the structure after many years of construction was comprehensively evaluated.The relevant research results not only clarify the key degradation mechanisms of aging hydraulic structures under complex hydrological and climatic conditions,but also provide engineering basis for the durability assessment,operation and maintenance,and reinforcement design of similar sluices and river-lake regulation structures.
