大坝混凝土耐久性预测模型

随着我国一带一路和西部大开发战略不断推进落实，一大批以混凝土坝、混凝土桥梁等为代表的基础设施将在西部地区修建，高寒是西北地区的典型环境特征。混凝土结构在高寒区受到冻融影响，其内部不可避免地会出现损伤并累积，混凝土的力学性能和耐久性会随着时间推移逐渐向不利的方向演变，并最终影响结构的服役寿命和安全性。课题组通过开展冻融作用后混凝土宏微观试验研究，分析不同冻融循环次数对混凝土宏观性能及微结构特征参数的影响，建立了基于微结构特征参数的大坝混凝土全生命期性能发展预测模型。

As China's Belt and Road Initiative and the Western Development Strategy continue to advance and be implemented, a vast number of infrastructure projects represented by concrete dams, concrete bridges and similar structures will be constructed in China's western regions. Alpine cold conditions are a typical environmental feature of China's northwestern regions. Concrete structures in these areas are subjected to freeze-thaw actions, which will inevitably cause internal damage and its progressive accumulation. The mechanical properties and durability of concrete will gradually deteriorate over time, ultimately compromising the service life and safety of the structures. Our research team conducted macro-micro experimental studies on concrete after freeze-thaw cycles, analyzed the effects of different freeze-thaw cycle times on the macroscopic properties and microstructure characteristic parameters of concrete, and established a prediction model for the full-life-cycle performance evolution of dam concrete based on the microstructure characteristic parameters.
