摘　　要：单向纵坡的斜拉桥对设计施工和稳定有较大影响,而对称双向纵坡与单向纵坡又有不同,针对彭溪河特大单向纵坡斜拉桥和相同跨度的对称双向纵坡斜拉桥进行了有限元仿真分析,为设计和施工提供了借鉴.The installation of longitudinal slope of a cable-stayed bridge has effects on the design, construction and stability of a bridge. But a symmetry double slop is quite different from a one-way slope. The model of Pengxi River Cable-stayed Bridge structure with one-way slope and that of a symmetry double slop bridge were analyzed with finite element analysis. It provides reference for the design and constructions of such kind.
