摘　　要：分析了采空区上方高速公路路基路面破坏的5个指标,即沉降、倾斜、水平位移、水平移动、曲率,以及5个指标之间的定量表达式;结合城市地下工程开挖相关控制指标,定量地研究了采空区上方高速公路路面的变形控制指标。综合国内外相关文献以及高速公路采空区路基施工稳定性评判指标,提出了适合采空区上方高速公路路基以及桥墩等允许变形的控制指标。There＇re 5 failure indicators for the road bed of expressway above the mined-out area, including subsidence, inclination, horizontal displacement, horizontal movement and curvature. Based on the analysis of these five indicators and their quantitative expressions, combined with relative indexes for excavation of underground project in cities, deformation controlling indexes were studied for the road bed of expressway above the mind-out area. Taking into consideration stability evaluation of the highway road bed above mined-out area, based on related document obtained at home and abroad, the controlling indicators were proposed for tolerable deformation of the expressway roadbed above the mind-out area.
