摘　　要：在对连续曲线箱梁桥试验研究的基础上,采用三维虚拟层合单元法对全桥进行空间有限元分析,计算结果与试验结果符合良好;该方法与过去传统的方法相比,具有引进的计算假定少、模型单元少且计算精度高等优点,完全能满足实际工程的需要。On the basis of the continuous curved box girder bridge experiments, this paper analyzes the whole bridge by the spatial method of three dimensional virtual laminated element. The comparision between the test and calculating results showed that they had a good agreenment. Compared with the conventional method, the proposed method has many virtues such as the computing suppositions are lesser, the total elements of the FEM model is lesser and the computing precision is higher and so on. The proposed method entirely meets with the practical engineering s requirements .
