摘　　要：润扬大桥的北锚采取带案投标方式 ,变更的建设方案与初设阶段方案有较大变化 ,本文对两方案作了锚体 -基础 -土体三维变形和应力的有限元分析比较 ,得出修改方案较原方案更经济合理 ,更适合施工 。The construction scheme of Runyang Bridge's north anchor is decided through bidding with the original scheme,and the modified scheme has been changed greatly.Based on 3 D FEM analysis,the two schemes are compared.The result is that the later is economical and has advantage in construction than the former.According to this,the later has been selected.
