| 摘 要： | 基于有限元数值方法对一船舶撞击连续梁承台群桩基础事故进行模拟，分析了不同上部结构约束、不同冲刷深度、不同荷载等级下群桩基础的受力变形特性。结果表明承台周围河床的冲刷深度对桥梁下部结构受力变形特性影响明显，冲刷深度的加大减弱了桥梁下部结构承受撞击能力。对该次事故结果作出评定，并提出该连续梁桥下部结构的撞击力限值，为桥梁运营养护提供参考。 |

| Abstract: | Based on finite element method, the accident of a ship collision with group-piles foundation of a continuous beam bridge is simulated. The mechnical and deforming behavior of group-pile under different super structural constraint, different scour depth, different load grade are analysed. The results indicate that the effect of scour depth on the deforming behavior of substructure is obvious, increased scour depth weaken the bridge substructure collision capability. At last, this paper assesses the consequences of this accident and puts forward the limited value of impact force, so as to provide reference to the bridge maintenance. |
| Keywords: | ship-bridge collision the bearing and deforming behavior finite element analysis group piles foundation |
