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.
