目前,混凝土桥梁建设主要的功能是为了确保交通的通畅,但部分桥梁在建成后,由于受气候、环境因素的影响,结构材料会被腐蚀和逐渐老化,并在长期荷载作用下强度和刚度逐渐降低,即耐久性不足问题困扰着桥梁建设。本文对施工阶段保障混凝土桥梁耐久性的措施进行深入探讨。 At present, the main function of concrete bridge construction is to ensure the smooth traffic. However, after some bridges are built, due to the influence of climate and environment, the structural materials will be corroded and aged gradually, and the strength and stiffness gradually decrease under long-term load Reduced, that is, lack of durability problems plagued the bridge construction. In this paper, the measures to ensure the durability of concrete bridges during construction are discussed in depth.
