摘要
以重庆綦江赶水大桥为工程背景,建立空间有限元模型。讨论了顶板在恒载(自重)、纵向预应力、顶板横向预应力、腹板竖向预应力的组合作用下的受力特点,对不同梁高的顶板应力进行分析比较,得出一些对设计和施工有意义的结论。
Taking Chongqing Qijiang Ganshui Bridge as the project background, the finite element model was established. The stress characteristics of roof under the combined effect of constant load （weight）, longitudinal prestress, roof transverse prestress, web vertical prestress were discussed, the roof stress of different beam depth was comparatively analyzed, drawing some meaningful conclusions for design and construction.
