高速公路混凝土桥梁典型病害产生原因及防治对策分析

摘要

桥梁是高速公路交通的重要组成部分，其中，混凝土桥梁在荷载、自然环境和偶然因素的共同作用下，材料性能、安全性能、耐久性能等都在下降，使得桥梁存在极大的安全隐患。为此，本文将通过对高速公路混凝土桥梁典型病害产生的原因展开分析，然后提出病害防治的对策。%Bridge is an important part of highway traffic, the concrete bridge under the joint action of load, natural environ-ment and accidental factors, its material performance, safety performance, durability and other are in decline, making the bridge there is a great security risk. Therefore, this paper wil analyze start with the causes of typical diseases of highway co-ncrete bridge, and then puts forward some prevention and cure countermeasures of diseases.
