| 摘 要： | 通常认为作为加筋的土工合成材料是不能承受剪力和弯矩的薄膜,在此前提下,首先导出了横向挠曲变形微小条件下的薄膜平衡微分方程.然后根据竖向位移与应力的连续性,将层状弹性体模型与薄膜方程相耦合,建立了土工合成材料加筋路面的计算模型.以两层加筋体系为例,导出了轴对称荷载作用下的一般解.并通过算例对模型的加筋效果进行了分析.

| Abstract: | Geosynthetics are usually regarded as a membrane which can not take shear and bend forces. Based on this, this paper firstly established the membrane equation on the assumption that the deformation of membrane is small. Secondly, a model of reinforced pavements was proposed by coupling the elastic multilayer foundation and membrane equation according to the continuity of stress and displacement. Finally, taking two\|layer reinforced pavements for example, the solution of reinforced pavements is given and the reinforcing effect is analyzed through a numerical example. |
