| 摘 要： | 该文以某预应力混凝土梁桥受船舶撞击的工程实例,采用简化模型、空间杆系有限元计算分析模型、空间实体有限元计算分析模型等三种计算模型分别评定船舶撞击对该桥受力行为的影响。针对桥梁受船舶撞击后,分步骤分析,为尽快通车,以及下一步是否需要对该桥梁进行加固设计提供依据。

| Abstract: | Taking an engineering case of a prestressed concrete bridge collided by ship as an example,the article uses three calculation models of the simplified model,the spatial bowstring finite element analysis model and the spatial entity finite element analysis model to separately assess the influence of ship collision on the bridge behavior subject to force.The article analyzes the bridge after ship collision by steps,and provides the basis for opening traffic as quick as possible and the next step of whether or not to carry out the reinforcing design of this bridge. |
