| 摘 要： | 该文采用有限元分析方法,分析横向预应力对箱梁顶底板正应力的影响。该文定义了一个交互影响系数k,交互影响系数的意义为截面在有横向预应力时的正应力与无横向预应力时的正应力之比,以此来描述空间力学效应的变化规律。 |
| 关 键 词： | 连续刚构桥预应力 横向预应力 交互作用 |

| Abstract: | The article analyzes the influence of transverse prestress on the normal stress of the top and bed plates of box beam by the finite element analysis method.The article defines a reciprocal effect coefficient k.The meaning of the reciprocal effect coefficient is the section ratio of the normal stresses with the transverse prestress and without the transverse prestress so as to describe the variable rule of spatial mechanics effect. |
| Keywords: | continuous rigid-frame bridge prestress transverse prestress interaction |
