摘　　要：为保证采空区上桥梁、桥下铁路及路堑边坡安全,采用自动化监测方案对跨鹤大铁路公路桥开展沉降、倾斜、水平变形和曲率的监测与分析。通过将观测站监测结果和桥位预计变形与已有规程规范对比估算破坏程度。结果表明目前桥梁状态良好,但采动影响预计会对桥梁变形造成一定破坏,需持续观测保障桥梁通行安全。To ensure the safety of bridges on the goaf,the railways under the bridges and the road cut slopes,the automated monitoring scheme is adopted to monitor and analyze the settlement,inclination,horizontal deformation,and curvature of the road bridge crossing the Heda Railway.The damage degree is estimated by comparing the monitoring results of the observation station and the predicted deformation of the bridge site with the existing regulations.The results indicate that the current condition of the bridge is good,but the influence of mining is expected to cause some damage to the bridge deformation,and continuous observation is needed to ensure the safety of bridge traffic.
