文章以《中山市干线公路网规划（2004-2030）》中规划的＂纵四线＂为背景,研究相跨径的预制小箱梁在不同桥宽下,下部结构的受力特点,并根据抗震计算结果选取相对合理的下部结构形式。根据项目要求和类似工程状况,提出了几种不同的下部结构形式,利用迈达斯2011结构软件进行抗震分析,科学地确定合理的下部结构形式。

Under the background of the so-called "Longitudinal Four Lines" Planed in "The Main Road Network in Zhongshan city(2004-2030)",the author studied the small box girder bridge in different span and different wide.According to the seismic computing requirements for relatively optimization of the structure of the relative form,this paper introduces project requirements and similar engineering condition,puts forward several proposals.Use the Midas 2011 structure software seismic analysis,and according to the corresponding technical and economic indexes of choice than science,uncertain economic and reasonable upper structure.
