以二郎河特大桥超高主墩大跨连续刚构的设计为背景,采用大型有限元程序,通过对目前常见的几种超高主墩形式,对稳定性、结构内力、经济性等关键技术问题做了较深入的分析与研究,提出了结构受力满足要求、经济性良好、施工方便的超高主墩结构形式,可为今后山区同类的高墩桥梁提供借鉴与参考。 Taking the design of large-span continuous rigid frame of super-tall main pier of Erlanghe Super Large Bridge as the background, large-scale finite element program is used to analyze the key technologies such as stability, internal force and economy of the existing common high- The author made a deep analysis and research on the problem, put forward the structural form of the ultra-tall main pier which is satisfied by the requirements of the structure, good in economy and convenient in construction, which can provide reference and references for similar high-pier in the mountainous area in the future.
