| 摘 要： | 混凝土浮箱桥在国外已得到较多应用，但在国内尚空白。将有限条元法用来分析混凝土浮箱桥，推导了弹性介质上有限条元的计算公式，并编制了相应的有限条元计算程序。在研究中发现用有限条元计算浮桥最大弯矩与跨矩的比值同弹性地基梁法所得到的比值几乎相等。

| Abstract: | Based on the finite strip method, this paper is to analyze the concrete pontoon bridges which have been put into use in some countries, yet remain a gap in china. The calculating formula of the finite strip on elastic media has been induced and programmed. The ratio of maximum bending moment and mid span obtained by this method is almost the same as that by the elastic footing beam method. |
