摘　　要：拱形水上升降式桥梁防撞装置能对拱桥易撞部位进行防护,并能随水位变化而升降。该防撞装置解决了山区河流拱形桥梁防船撞的难题,适用于山区河流拱形桥梁的防撞工程。为保证该装置运行的可靠性,对防撞装置的防撞带模型进行试验研究。通过水工模型试验与有限元模拟的方法研究的结果表明,防撞带模型结构整体刚度与原型相似,验证了模型与原型的相似性。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.
