| 摘 要： | 采用各向同性的大挠度薄板建模,利用三维有限元分析方法,对桥面铺装设计中的关键参数进行讨论,探讨不同参数组合条件下铺装层内部受力分布的影响,有限元分析结果表明,沥青混凝土铺装层厚度,粘结层模量对铺装层内部以及铺装层与粘结层界面的剪应力影响最为显著,桥面铺装设计厚度设计宜在10～12 cm,同时设置必要的防水粘结层。

| Abstract: | The 3D finite element method was used to study the critical parameter(stress and strain) about conctrete bridge pavement using the isotropy large deflection model.The finite element analysis indicate that asphalt concrete thickness and waterproof layer modulus have significant influence on stress distribution inner or between the concrete pavement and waterproof layer,the reasonable thickness is 10~12cm,the waterproof layer should be optimally designed. |

| Keywords: | finite element concrete bridge pavement waterproof layer modulus thickness |
