随着公路、铁路交通的不断发展，钢筋混凝土或预应力混凝土桥梁占据了全国桥梁的绝大多数。经多年使用后，部分桥梁病害严重，不得不重建或加固。文章结合目前桥梁加固现状，提出了灌浆、植筋、施加体外预应力的旧桥加固施工技术，并详细介绍了施工要点，为桥梁加固提供了一些经验，对桥梁加固具有一定的参考价值。
隨著公路、鐵路交通的不斷髮展，鋼觔混凝土或預應力混凝土橋樑佔據瞭全國橋樑的絕大多數。經多年使用後，部分橋樑病害嚴重，不得不重建或加固。文章結閤目前橋樑加固現狀，提齣瞭灌漿、植觔、施加體外預應力的舊橋加固施工技術，併詳細介紹瞭施工要點，為橋樑加固提供瞭一些經驗，對橋樑加固具有一定的參攷價值。

With the continuous development of highway and railway transportation ,reinforced concrete or prestressed con-crete bridges become the majority of the bridges nationwide .After years of operation ,some bridges are damaged so badly that they have to be rebuilt or reinforced .Based on the current situation of bridge reinforcement ,a new reinforcement construction technique for the damaged briges was put forward .It combined the application of grouting ,steel bars and ex-ternal prestressing .And then the key points of construction were introduced in detail .This study will provide some guid-ance for the bridge reinforcement ,which has certain referential value to the reinforcement construction .
