对高速公路不同于普通建筑物的特殊性进行了分析。根据开采沉陷影响下高速公路断裂破坏的原因，提出以曲率作为研究高速公路容许变形的指标。基于对高速公路断裂破坏前结构状态的分析，利用力学理论推导出高速公路容许曲率的计算公式，建立了同时考虑高速公路结构特征及修筑材料特性的开采沉陷影响下高速公路结构安全性判断方法，并计算出我国常规水泥混凝土路面高速公路的容许曲率区间。

Influenced by mining subsidence, the difference of expressway from common buildings was analyzed. It was put forward that applying curvature to be the index of expressway admissible deformation on the basis of expressway breakage cause. By analyzing struc-ture state of expressway before breakage, applying mechanics theory to deducing calculation formula of admissible curvature deforma-tion, the structure safety criterion of expressway influenced by mining subsidence was set up which simultaneously considered express-way structure and building material characteristic. With the formula, admissible curvature deformation section of Chinese expressway paved by conventional cement was calculated.
