| 摘 要： | 结合佛(山)开(平)高速公路拓宽工程,运用有限单元法分别模拟计算了高速公路拓宽工程新老路基发生差异沉降时沥青混凝土路面、水泥混凝土路面两种路面结构的应力状态,对差异沉降引起的路面结构层不同位置、水泥稳定碎石层中的附加拉应力和剪应力进行分析,并提出了新老路基差异沉降控制标准。

| Abstract: | Finite element method was used to calculate the stress states of asphalt pavement structure and concrete pavement structure respectively in the condition of differential settlement between new embankment and old embankment, and to analyze the additional tensile stress and shearing stress of different layers in the pavement and of steady broken stone-cement layer, which are both caused by the differential settlement. The controlling standard of differential settlement in expressway extension project was also put forward. |
