处于库区的石拱桥桥台长期受水侵浸泡,经过一段时间的运营,两岸桥台前墙出现竖向贯通裂缝,为解决通车条件下高填土桥台的加固问题,采用预应力对穿锚索和台后注浆方法对桥台进行加固,通过对结构进行计算分析等,证明所采用的加固设计方法可行,本工程为类似桥梁病害的处治提供借鉴。 Stone Arch Bridge abutments in the reservoir area have been soaked in water for a long period of time. After a period of operation, the vertical crevices of the abutment walls of the two sides of the Strait appear vertically. In order to solve the problem of reinforcement of high fill abutments under the open conditions, Anchorage cable and back grouting method to reinforce the abutment. Through the calculation and analysis of the structure, it is proved that the reinforcement design method adopted is feasible. This project provides reference for the treatment of similar bridge diseases.
