| 摘 要： | 利用通用有限元软件对三跨预应力混凝土连续梁桥的沥青混凝土铺装进行应力分析，通过荷载不同位置下的沥青混凝土铺装层拉应力、剪应力分析，确定出荷栽的最不利布置位置。分析荷载最不利布置下铺装层模量对铺装层拉应力及层间剪应力的影响规律，为桥面铺装层材料选择及研究提供参考。

| Abstract: | The paper uses the finite element software to analysis the stress of bridge deck pavement of pre-stressed concrete bridge,to analysis the tensile stress and the shear stress under the different load location,and to find the most disadvantaged load location,and analysis the effect of material modulus on tensile stress and shear stress under the most disadvantaged load location. The helpful material modulus is recommended. |
