锚喷混凝土变双曲拱型结构为箱型结构加固双曲拱桥

Changing the Double Curved Arch Type Construction by Concrete Anchoring and Spraying to Reinforce Double Curved Arch Bridge

双曲拱桥作为上世纪七、八十年代大量修建的桥梁,目前还有很多仍在使用。因当时设计荷载普遍较低,目前多数面临加固提载问题,介绍了将双曲拱式受力结构转换为箱型结构的全新加固方法。

Double curved arch bridges were largely built ones in 1970s and 1980s, but a lot of them are in use at current. On account of that time, the design load was universally lower, multitude of them are faced with reinforcing issue to increase loading at current. The paper introduces changing the double curved arch type construction into box type construction, that is a fully new method for reinforcement of double curved arch bridge.
