| 摘 要： | 采用有限元方法和结构力学方法对圆管涵进行力学分析，通过对2种方法之结果的比较，定量分析了早几年圆管涵普遍开裂的原因。在此基础上提出一种圆管涵的合理结构形式，并介绍了这种结构形式在实际应用中的良好效果。理论和实践证明，提出的这种结构形式具有优良的结构承载性能。

| Abstract: | This paper adopts the Finite Element Method and the structure Mechanics method respectively to analyze the mechanical behavior of circular pipe culverts. By comparing the results from two methods with each other, the cause is analyzed quantitatively which led the culverts to crack extensively a few years ago. Based on it, a reasonable structural form of circular pipe culverts is developed and the good effect of this form in practice is introduced. Both the theory and the practice show that the structural form in this paper has the excellent load bearing capacity. |
