Study on the Treatment and Monitoring Method of Existing Urban Rail Transit Bridge Support
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 threaten-ing 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.
