某公路U型桥台病害原因分析及加固设计

Disease analysis and reinforcement design of a highway U-shaped abutment

采用ANSYS软件建立了桥台三维有限元模型,研究了裂缝成因及加固措施,结果表明:桥台在设计荷载作用下的受力状态良好,强度满足要求,通过采取桥台填料换填、注浆以及桥台前墙加固,并改造路面搭板等措施,达到了预期的加固效果。

Based on ANSYS software, this paper built a 3D FEM model to analysis disease reasons and propose reinforcement method. Results show that the mechanical behavior of the abutment under design load is good, structural strength meets design requirements. Through adopted measures include abutment filling replacement and grouting, the front wall of abutment and pavement slab strengthing, so as to achieve expected reinforcement effect.
