In order to improve the accuracy of continuous beam bridge deformation monitoring,the engineering project can introduce multisensor fusion technology to carry out the design of Deformation monitoring method for long-span continuous girder bridges.The horizontal,vertical and inclined sensors are arranged at the monitoring points of the continuous beam bridge to collect the deformation data of the beam bridge in real time,assist the whole station and the triangle height measuring device,calculate the settlement and deformation of the large-span continuous beam bridge,and complete the design of the monitoring method.The comparative experimental results prove that the designed monitoring method has good effect in practical application,and this method can control the deviation of the monitoring results of continuous beam bridge deformation by<2mm,so that the monitoring results can meet the requirements of high precision.
