In order to ensure the safe operation of the high-speed train on the bridge, the real-time monitoring of the technical condition of the bridge is necessary, and various measures are needed to be taken to ensure that the bridge structure is always in a good working state.
The support is used as an important component of the bridge structure and mainly plays a role in transmitting the dead weight of the bridge and the load on the bridge to the foundation of the abutment and adapting to the deformation capacity of the bridge. Most of the high-speed railway bridges are box-shaped simply supported girder bridges and continuous girder bridges, wherein the number of the simply supported girder bridges is the largest, 4 supports are arranged on each box girder, and 300-500 t spherical supports are adopted. After the bridge is built, the bridge support is a first route for transferring load on the bridge from top to bottom, mainly bears the dual functions of bridge dead weight and train load, is also affected by temperature, natural disasters, impact and the like, and can cause a series of diseases due to long-term large-tonnage load action, so that the condition of a bridge structure is changed, the safety problem of the support is directly related to the operation safety of the bridge structure, and the safety of the support is important. Therefore, the working state of the bridge can be monitored by monitoring the counter-force change condition of the bridge support in real time, and whether the bridge is in a normal range or not is judged.
At present, an intelligent force measuring support which has simple structure, definite stress, good durability and low manufacturing cost and can be used for large-tonnage high-speed railway bridges is not available at home and abroad. The existing intelligent support has the defects of complex structure, high manufacturing cost, incapability of large-area popularization and application and the like.
