正交异性钢桥面铺装不同于普通的高等级路面，它结构特殊，受桥面板的工作性能、外界气候、温度等的影响很大，容易产生各种病害；国内外对桥面铺装问题，从材料的研制，正交异性钢板的结构优化，以及施工工艺的改进等各方面，都进行了深入的研究，这些对正交异性钢桥面铺装设计和工程应用都具有重要的意义。
本文以厦门马新大桥的正交异性钢桥面与铺装层为研究对象，利用大型通用有限元软件ANSYS对正交异性钢桥面板和钢桥面板铺装层的力学性能进行分析研究；结合仙岳路高架改造工程钢桥面铺装层疲劳试验和静力试验研究，分析正交异性板与铺装层的疲劳性能和受力情况。

现代大跨度悬索桥和斜拉桥的加劲梁大多数采用流线型钢箱梁，其桥面多采用正交异性板，正交异性钢桥面板技术已经成为衡量一个国家钢桥技术水平的重要标志，随着桥梁跨径的增大，在桥梁工程中的应用也会更广泛。桥面铺装体系是桥梁行车系的重要组成部分，它的好坏和使用耐久性直接影响到行车的安全性、舒适性、桥梁投资效益和社会效益。由于钢桥面具有刚度较小，局部变形大，钢板热容量小，温度变动范围大，钢板易锈蚀等特性，因而，钢箱梁桥面铺装是一项十分复杂的综合技术。

首先，建立正交异性钢桥面铺装体系力学分析模型，分析桥面铺装在车辆荷载作用下的受力特性，确定最不利荷位，并研究正交异性钢桥面铺装层的应力应变分布规律；其次，通过改变有限元计算模型中的设计参数，分析正交异性桥面板几何尺寸、铺装层厚度、弹性模量以及剪力钉的尺寸和布置形式等各参数与钢桥面铺装层受力性能的对应关系；最后，通过对仙岳路高架改造工程钢桥面铺装层进行理论计算和疲劳试验，根据循环荷载作用下试验模型疲劳次数、疲劳损伤开裂部位，计算得到桥面铺装的疲劳寿命，分析疲劳损伤主要成因；通过对仙岳路高架改造工程钢桥面铺装层进行理论计算和静力试验，得出钢桥面铺装及钢箱梁顶板各层应力及剪力钉受力情况，分析并验证了钢纤维混凝土和剪力钉对钢桥面铺装层竖向刚度和抗剪刚度的影响。
