摘要
针对当前大秦铁路扩能工程,由于股道增加,个别桥涵运营荷载超出其原设计荷载,需对其进行加固。本文通过分析盖板涵工点的两个加固方案,建立有限元模型进行受力分析,最终给出了合理加固建议。
According to the capacity enhancement project of Daqin Railway, the tracks are added and the loads of some bridges and culverts change. As a result, it needs to be reinforced. The thesis analyzes the two reinforcement methods through finite element model and makes a suggestion.
