bedding rock slope is the most common slope type in highway and bridge construction in mountainous areas in Southwest China. Taking the bedding rock slope section of zhangyoufang bridge as the research object, this paper uses Mida GTS finite element software to establish a three-dimensional geological model, and discusses the influence of pier characteristics on pier stress and deformation. The calculation shows that the increase of rock socketed depth, pile diameter and pier stiffness within a certain range can effectively improve the vertical bearing capacity of pile foundation and reduce the displacement of pier top. Hollow thin-walled pier has the highest safety factor. Compared with single pier and double column pier, the stress of pile column double row pier is more reasonable and reliable. Finally, the results of orthogonal test calculation show that the pier structure and pile diameter are the biggest influencing factors of horizontal displacement and vertical displacement respectively.
