本文应用ANSYS有限元对不同界面型式的桥面铺装力学进行了分析与计算,不同沥青铺装层模量、不同铺装层厚度对层间稳定性的影响,分析表明:露石界面铺装结构可以有效地传递面层荷载,分担了面层的荷载压力,从而提高了铺装层的使用寿命;露石界面铺装结构相对于传统界面铺装结构可以减小层间剪应变及节点的相对位移,大幅提高了桥面铺装结构层层间的稳定性;增加面层弹性模量和面层厚度有利于提高铺装结构层层间的抗剪性能及混凝土桥面铺装的耐久性能。
In this paper, ANSYS finite element analysis of different interface types of deck pavement mechanical analysis and calculation of different asphalt pavement modulus, the influence of different pavement thickness on the stability of the interlayer analysis shows that: exposed stone pavement The structure can effectively transfer the surface load and share the load pressure of the surface layer, thereby increasing the service life of the pavement layer. Compared with the traditional interface pavement structure, the exposed stone interface pavement structure can reduce the interlaminar shear strain and the node The relative displacement greatly improves the stability of the deck pavement structure layer. Increasing the elastic modulus and the thickness of the surfacing layer are beneficial to improve the shear resistance between the pavement layers and the durability of the concrete deck pavement. .
