为了研究下伏采空区对地表高速公路变形影响，采用现场监测、数值模拟和正交试验分析手段对下伏采空区对地表高速公路影响进行了研究。得出结论：①随着采空区倾角不断增大和随着深厚比的增加，高速公路的残余沉降变形量及变形范围呈逐渐减小趋势；②充填程度越好控制变形能力也就越强，对地表高速公路的影响也就越小，而达到一定充填度时一味增加充填量，对于地表残余变形的控制差异不会太大。③通过正交试验分析得出影响显著性由大到小为采空区倾角、深厚比、充填程度。

In order to study the effects of goaf on highway deformation, a research combining on-site monitoring, numerical simulation and orthogonal experiments of goaf was carried out. The results can be concluded as follows. With the increase of goaf inclination and depth to thickness ratio, re-sidual deformation and deformation range of highway is gradually decreased. The better the filling degree is, the stronger the ability to control the deformation and the smaller the impact on highway will be. When the filling reaches a certain degree, increasing the amount of filling to control the re-sidual deformation will do no difference. The orthogonal experiment indicates that the influence of goaf inclination angle, depth to thickness ratio and filling degree on highway deformation decreases one after another.
