铁路桥梁工程混凝土耐久性的研究、设计应用及发展趋势

Research, Design Application, and Development Trends of the Concrete Durability in the Railway Bridge Engineering

建筑业作为国家经济发展关键驱动力,已经具有成熟的技术和经验。随着社会的不断进步,建筑行业的范围也在逐渐扩大,并对其所涉及的工程寿命及质量要求也越来越严格。经过历年来的不断试验与积累的经验,充分证明了混凝土的耐久性是铁路桥梁工程质量的最主要因素之一。我们要不断探索铁路桥梁工程中混凝土耐久性,更要重视全寿命设计的宗旨,加强环境资源保护、节约不可再生资源,才能发挥国民经济持续发展的重要意义。

As a key driving force of the national economic development,the construction industry has had mature technology and experience.With the continuous progress of society,the scope of the construction industry is gradually expanding,and the requirements for the service life and quality of the projects involved are becoming increasingly strict.Through years of continuous experimentation and accumulated experience,it has been fully proven that the durability of concrete is one of the most important factors affecting the quality of railway bridge engineering.We need to explore the durability of concrete in railway bridge engineering constantly,pay more attention to the purpose of whole life design,strengthen the environmental resource protection,and save the non-renewable resources,in order to play an important role in the sustainable development of the national economy.
