摘　　要：为更好研究夹层橡胶隔震结构在连续曲线箱梁桥中的作用,文章探讨了一种箱梁单元,考虑翘曲效应影响,其增加了一个翘曲位移自由度,同时考虑形心与剪心不重合的偏心影响,对照非隔震结构,对比分析夹层橡胶隔震结构的隔震效果。In order to better study the role of laminated rubber isolation structure in continuous curved box girder bridge, a box girder element is considered. Considering the effect of warping, it adds a degree of freedom of warping displacement. And the eccentricity of non - co- incidence with shear center, the isolation effect of sandwich rubber isolation structure is compared with that of non - isolated structure.
