摘　　要：通过在采空区上部区域布设变形监测网,以监测高速公路建设到运行期间采空区及大桥基础的活动,分析注浆减沉后采空区残余移动变形的实测数据及注浆减沉效果,研究采空区残余移动变形对地表及大桥的安全稳定性影响。The activities of the goaf and the foundation of the bridge during the periods of construction to operation of the highway was predicted by the deformation monitoring network that layout above the goaf. From this,the paper analysis the grouting reduce effect and the measured data of the remained movement deformation in goaf after grouting,and research the security stability impact of the remaind movement deformation to the earth surface and the bridge.
