摘要
为了保证圬工拱桥的桥墩在改造过程中不被破坏,应选择合理的上部结构拆除方案。结合一座3跨连续圬工拱桥,在上部结构拆除过程中,对桥墩进行受力分析,得出墩顶的水平位移和墩底截面的最大应力(最大压应力和最大拉应力),以选择合理的拆除方案。
A reasonable dismantled plan of superstructure is chose,to ensure pier of the masonry arch bridge don’t be destruction in dismantled process.In combination with a triple articulation masonry arch bridge,force analysis of pier of the bridge is implemented in reconstructed process of superstructure.Horizontal displacement of the bridge pier and maximum stress（maximum pressure stress and maximum tensile stress） are calculated,to choose a reasonable dismantled plan.
