支座是桥梁结构承受并传递荷载及变形的重要构件,对桥梁功能的发挥起着至关重要的作用。然而由于各种原因,在运营中支座经常出现各种病害甚至影响桥梁的正常使用。某连续刚构桥的支座存在影响桥梁功能的病害,不得不进行梁体顶升、支座维护。该文结合工程项目,详细介绍某桥支座维护设计及施工要点、监控实施等,供类似工程参考。 The bearing is an important component that the bridge structure can bear and transmit the load and deformation, which plays a crucial role in the function of the bridge. However, due to various reasons, bearing often appear in the operation of various diseases and even affect the normal use of the bridge. A continuous rigid frame bridge bearing the existence of the bridge function of the disease, had to carry out the beam lifting, bearing maintenance. This article combined with the project, details the maintenance design and construction of a bridge support points, monitoring implementation, for similar projects for reference.
