| 摘 要： | 利用有限元软件ANSYS，对新建歌乐山铁路四线双柱式桥墩由于冲撞而造成的局部破损进行了有限元分析。根据规范采用不同的荷载组合，对桥墩受到的落粱冲击应力、桥墩稳定性及受损桥墩的强度进行了详细有限元分析，以检验桥墩受损后其承栽能力能否满足运营安全要求，并为桥墩的维护和保养提供理论依据。

| Abstract: | The paper makes spatial finite element analysis about the partial breakage because of dash of double-column pier of the new built Geleshan four-lane railway bridge. The inpact sress of the pier, the stability and the strength are analyzed in detail according to different loads combination of the code to determine weather the load capacity of the damaged pier satisfies the safety transportation requirements. The analysis also can supply theoretical foundation to the maintenance of the pier. |
