摘　　要：以广东省某山区高速公路上的一处双柱式墩为例,分析其在横向陡坡路段下的受力状况,并通过有限元分析软件进行对比验证,依据现行公路桥梁相关规范对该墩进行配筋验算,同时对几种不同墩高差下的墩柱进行了对比,其方法和结论可为同类桥墩设计提供参考和借鉴。Combined with a double column pier of mountainous highway in Guangdong Province as an example, this paper analyzed its stress state in the transverse steep slope sections. It also compared and verified that through the finite element analysis software, and had the reinforcement calculation of the pier according to the current highway bridge related specifications. At the same time, it compared the pier column with different height of pier. Its methods and conclusions can provide some reference for the similar bridge pier design.
