摘　　要：本文采用试验的方法对格构增强复合材料桥梁防撞装置的侧向抗冲击性能进行研究。研究横向格构间距对复合材料圆筒体冲击极限荷载、冲击最大位移、耗能性能的影响,并根据试验数据进行数值拟合,得出格构间距对极限荷载的拟合曲线。试验中横向格构越密,极限压缩荷载或极限冲击荷载越大。In this paper,lateral impact resistance of lattice-reinforced composite bridge anti-collision device is studied by experimental method.The spacing of transverse lattice effects of the impact ultimate load,maximum displacement and energy dissipation performance of composite cylinders are analyzed.Numerical fitting is carried out according to the test data.The fitting curves of lattice spacing to ultimate load are obtained.The results show that the tighter the transverse lattice in the test,the greater the ultimate compressive load or ultimate impact load.
