论公路旧桥的加固与管理

Reinforcement and Management of Old Road Bridge

随着我国交通运输业的快速发展,过去修建的桥梁,现在承受着大量超预期的交通荷载。在经受洪水的洗礼以及车辆船只的碰撞后,很多桥梁产生了潜在的安全隐患,其正常状态已受到了破坏。因而,对旧桥进行加固,不仅可以进一步提高桥梁的承载能力,也可以增强其安全性,具有重要的现实意义。

With the rapid development of China＇s transportation industry, the bridges built in the past have to bear heavy traffic loads. Having been baptized by floods and hit by vehicles and vessels, many bridges are now threatened by potential safety hazards, which destroy the normal state of the bridges. Therefore, the reinforcement of old bridges can not only further improve the carrying capacity of the bridges, but also enhance the safety of them, which has important practical significance.
