摘要研究目的：正交异性板及桥面复合铺装由多层次结构和多种材料构成，局部受力非常复杂，而目前国内对其研究多偏重于理论计算，缺乏相关的试验验证。为掌握结构真实受力情况，本文在理论计算的基础上，以厦门某桥为工程背景，进行由正交异性板、栓钉和混凝土铺装层组成的桥面复合铺装的影响面加载试验，以验证相关计算理论和计算方法。研究结论：（1）正交异性板及桥面复合铺装影响面试验与有限元计算结果基本吻合，表明本次试验方案能够较好反映出正交异性板及桥面铺装各结构层次的影响面分布规律；（2）桥面铺装结构影响面分布具有强烈的局部效应，三个典型部位横向影响范围基本在1～3个U肋间距长度之间，纵向影响范围约在5个U肋间距长度，但纵、横向影响较大区域基本都在1个U肋间距长度以内；（3）本研究方法及成果可为正交异性板及桥面复合铺装的设计和科研提供借鉴。

Abstract：Abstract：Research purposes： The orthotropic plate and the bridge deck pavement is composed of multi-level structure and a variety of materials，the local stress is very complicated. However，the current domestic research on it more focus on the theoretical calculation, the relevant test is little. In order to master real stress distribution of the structure, on the basis of the theoretical calculation, taking a bridge in Xiamen as the background, this paper carried on influence surface loading test of the bridge deck pavement by the orthogonal plate, studs and concrete pavement layers, to verify that the related theory and calculation method.
Research conclusions：It shows that the results of test agree well with the calculated results. The testing scheme can better reflect the distribution of the orthotropic plate and the bridge deck pavement structure level. The bridge deck structure has a strong impact on the surface distribution of local effects, the impact of three typical lateral positions is in the range of 1～3 U-ribs span length, the scope of the longitudinal is about 5 U-ribs span length, but the vertical and horizontal impact within a large area is substantially in 1 U-rib pitch length. The research methods and results can provide reference for design and research of the orthotropic plate and the bridge deck pavement.
