橡胶缓冲装置对斜拉桥及引桥碰撞影响研究
Influence of rubber buffer devices on collision between a cable-stayed bridge and its approach span
【摘要】 针对大跨度斜拉桥与引桥之间碰撞研究不深入、对斜拉桥与引桥之间防碰撞措施研究不系统等问题,研究橡胶缓冲装置对斜拉桥与引桥之间碰撞响应的减震效果,分析橡胶缓冲装置结构参数对斜拉桥与引桥之间碰撞响应的影响规律。
【Abstract】 The seismic behavior study of cable-stayed bridges at home and abroad is relatively perfect,and abundant achievements have been obtained.The aseismic performance of a cable-stayed bridge ordinarily can meet aseismic requirements,but cable-stayed bridge expansion joint damages and approach bridge beam collapses often happens under earthquakes.The study on the collision between a cable-stayed bridge and its approach span is not deep,and the anti-collision measures study is not systematical.Here,the shock absorption effect of rubber buffer devices on impact responses between a cable-stayed bridge and its approach span was investigated.The influence law of rubber buffer devices structural parameters on impact responses between a cable-stayed bridge and its approach span was analyzed in detail.
