摘　　要：盖梁在预应力作用下会影响曲线连续梁的结构受力,论文结合相关工程实例,通过有限元软件进行计算分析,结果表明,盖梁位置的主梁应力水平呈现曲线外侧低、内侧高的分布,相邻边支座其曲线内侧支反力小于曲线外侧,与曲线连续梁结构应力、支反力分布规律恰好相反。Cover beam under the action of prestress will affect the structure of the curve continuous beam,the paper combined with related engineering examples,through the finite element software calculation analysis,the results show that the position of the position of the main beam stress level outside curve low,inside high distribution,the inside of the adjacent edge support is less than the outside of the curve,and the curve continuous beam structure stress and reaction distribution pattern.
