摘　　要：采用两步分析法对118 m下承式钢管混凝土系杆拱桥拱脚进行了应力分析,用接触面单元模拟了拱肋钢管壁与拱脚混凝土之间的受力情况,计算了拱脚在最不利荷载的工况下的受力情况,提出了便于监控的控制点,为以后的拱脚施工监控提出参考。The paper analyzes the arch springing stress of the 118 m through supported steel pipe concrete tied arch bridge by applying two-step analysis method, simulates the stress conditions of arch rib steel pipe wall and arch springing concrete with connection surface unit, calculates the stress conditions of arch springing under bad load conditions, and finally puts forward convenient monitoring control point, which has provided some guidance for future arch springing construction monitoring.
