摘要
中、下承钢筋混凝土箱形肋拱桥是20世纪90年代工程界比较常用的一种拱桥形式,经过20多年的运营后,许多桥梁桥面系和吊杆等出现了较严重的病害,且具有较强的普遍性。鉴于此类桥梁大多数开始面临工程改造或大修,结合太原市漪汾桥改造工程的实例,对目前钢筋混凝土箱肋拱桥出现的病害特征、维修改造的设计施工要点,以及所采用的施工监控技术等进行了简要介绍和总结,可供同类项目借鉴和参考。
Half through or through arch bridge is common bridge type in the engineering field during the last decade of the 20th century, After the approached twenty years＇ application, the common diseases have appeared and are very serious on the deck system and suspenders. Whereas the maintenance and im- provement of this bridge type has became the focus. In this paper taking the improvement project of Taiyuan Yifen Bridge as an example, it is concisely introduced and summarized on the distress characteris- tics, the design points of the maintenance and improvement, and the advanced technology of construction monitoring and controlling to provide references for designers engaged in relevant area.
