摘　　要：通过研究U形桥台的开裂现象,提出采用拉筋法加固桥台的思路,着重进行了拉筋法加固U形桥台的数值分析,分析结果验证了拉筋法加固桥台的合理性和可推广性,并且确定了拉筋布置的最佳位置。By a studying of the fracture phenomenon on U-shaped abutment, putting forwoard the thought that adoptting the lacing wire method to reinforce abutment. It pays more attention to have a numerical analysis on reinforcing the U-shaped abutment by lacing wire method. The analysising results shows the rationality and generalizability of reinforcing the U-shaped abutment by lacing wire method. At the same time, it also defines the best position of arrangement.

关 键 词：桥台加固 拉筋法 数值分析 最佳位置
