【Abstract】 The arch-shaped water-lifting bridge anti-collision device developed protects the vulnerable parts of the arch bridge and can be raised and lowered according to the change of the water level. The anti-collision device solves the problem of anti-collision of arch bridges in mountain rivers and is suitable for anti-collision engineering of arch bridges in mountain rivers. In order to ensure the reliability of the operation of the device, it is necessary to conduct an experimental study on the anti-collision belt model of the anti-collision device. The hydraulic model test and finite element simulation were used to study the overall stiffness. of the anti-collision belt model structure. Results show that the overall stiffness of the anti-collision belt model structure is similar to that of the prototype, which verified the similarity of the model to the prototype.更多还原
