摘要： 由于监督管理不到位、施工设计不合理等原因，临近工程修建造成既有高速公路桥墩发生变形破坏，影响高速公路的正常运行，甚至可能导致安全事故。为此，对桥墩病害进行分析，确认破坏最严重点，运用FLAC3D软件建立有限元数值模型，通过有限元法对变形严重部位进行分析，确定桥墩的受力特征，针对性的确定监测方案，最终通过监测结果提出有效的治理建议。

Abstract: Adverse deformation and damage at the existing highway bridge piers were observed, and it was concluded that these deformations were induced by the adjacent construction. These excessive deformations and damages might affect the safe operation of the highway and even result in serious traffic accident. The damages on the bridge piers were numerically analyzed by commercial software FLAC3D. The stress and strain fields of the piers were evaluated, and the construction monitoring program was established from the numerical analysis results. Based on the monitoring results, bridge management decision could therefore be made.
