摘　　要：采空区造成地层缓慢沉陷,严重地威胁着地表建筑物的安全。在其沉陷过程中,上覆各岩层破坏特点、厚层坚硬岩体抵抗沉陷的作用等对最终沉陷有重要影响。采用数值模拟技术,具体深入地分析了地层的沉陷过程、注浆治理的效果,以及其主要影响因素,发现坚硬厚岩层发挥了关键作用。The gradual settlement above old goaf threatens the safety of surface buildings. Because freeway has strict demand on foundation settlement and undulation as well as slope, it is a difficult problem to built freeway on the surface above old goaf in engineering geologic field. Adopting numerical simulation, this paper analyses the settlement process of strata above old goaf and the effect of grouting , and accesses the engineering geology adaptability of building freeway on surface above Yexi old goaf.
