摘要 在役运营桥梁受船舶撞击的事故时有发生,轻者桥梁受损,重者桥梁垮塌,严重影响船舶通行安全和桥梁的运营安全。以某工字梁桥主梁受船撞损的病害为例,结合有限元计算,通过模拟船撞作用位置及撞击力大小,分析撞损病害产生的机理,并根据分析结果提出相应的加固设计方案。 The accidents of ship collision to bridge under service often occur. The light is bridge damage, and the serious is bridge collapse, which will seriously affect the traffic safety of ship and the operation safety of bridge. Taking the collision disease of the main girder of I-shaped beam bridge and ship as an example,combined with the finite element calculation, and through the simulation of ship collision role location and the size of impact force, the article analyzes the mechanism of collision damage and puts forward the corresponding reinforcement design scheme based on the analysis result.
