本文通过实桥试验的量测数据与空间实体单元有限元法的分析计算结果进行了比较,证明弯拱桥的空间受力状态是很明显的。按空间实体单元有限元法计算弯拱桥,能够较好地符合结构的实际受力状态。
In this paper, the comparison between the measured data of real bridge test and the finite element method of space solid element shows that the space stress state of curved arch bridge is obvious. According to the calculation of curved arch bridge by the finite element method of spatial solid element, it can well conform to the actual stress state of the structure.
