中文摘要：
为了满足桥梁加固、拓宽处理需求,介绍了使用增设钢悬挑梁拓宽这一方法进行拓宽时,在建立有限元模型过程中所遇到的模型边界条件的处理方式.通过建立三种有限元模型,对比得出边界条件为替换边界时,模型能更加真实地反应出桥梁实际的受力及位移情况.为以后这种类型的模型的建立提出了一种新的细节处理方式.
英文摘要：
To reinfore and expand bridges to meet the increasing traffic demands,the method of broadening with steel cantilever beam is introduced to hadle with the boundary conditions in finite element model.Compared with the three models of the study,a alternative boundary model gives more practical informations,which shows a new way to deal with similar problems.
