摘要
随着运营线路逐渐趋近设计的远期负荷,城市轨道桥梁的维修和加固成为人们关注的热点之一。桥梁支座病害是轨道交通最为普遍的桥梁病害之一,极大地威胁桥梁结构和运营安全,桥梁支座病害治理已经成为桥梁养护维修的重要工作。在桥梁支座治理期间,怎样保证施工的准确性并且不影响第二天的正常运营,因此产生了支座治理期间的监测工作。目前城市轨道交通桥梁顶升施工法进行支座更换最为常用,而在此期间采取什么样的监测手段能够满足施工现场要求成为重点。本文依据现有先进监测手段进行应用研究,为既有城市轨道交通桥梁支座治理期间的监测工作提供方法及手段参考。
As the operating lines gradually approach the designed long-term load,the maintenance and reinforcement of urban rail bridges has become one of the hotspots of attention.Bridge bearing disease is one of the most common bridge diseases in rail transit,greatly threatening the safety of bridge structure and operation.The treatment of bridge bearing disease has become an important work in bridge maintenance and repair.During the bridge support treatment period,how to ensure the accuracy of construction without affecting the normal operation of the next day has led to monitoring work during the support treatment period.At present,the lifting construction method of urban rail transit bridge beams is the most commonly used for bearing replacement,and during this period,the key is to adopt what monitoring methods can meet the requirements of the construction site.This article conducts application research based on existing advanced monitoring methods,providing methods and reference for the monitoring work during the treatment of existing urban rail transit bridge bearings.
