摘 要:总结了我国铁路混凝土结构耐久性的发展历程,介绍了我国铁路混凝土结构耐久性的保障方法,并结合现阶段我国铁路工程建设特点,指出了铁路混凝土结构耐久性依然面临服役环境复杂化、原材料资源短缺和过早劣化等挑战,提出了铁路混凝土结构耐久性长寿命化、定量化、智能化和可预测性的发展趋势。
Abstract: The development history for the durability of railway concrete structures in China is summarized, and the guarantee methods for the durability of railway concrete structures in China is introduced. Based on the characteristics of railway engineering construction in China at the present stage, it is pointed out that the durability of railway concrete structures still faces challenges, such as complicated service environment, shortage of raw materials and premature deterioration. The development trends of longer service life, quantification, intelligentization and predictability for the durability of railway concrete structures are put forward.
