| 摘 要： | 随着高等级公路的兴建和城市建设的进一步发展，平面曲线桥梁应运而生，刚构连续弯板桥成为有力竞争桥型之一．为了研究刚构连续弯板桥的空间受力特性，本文结合一实例刚构连续弯板桥，针对平面软件分析弯桥的不足，首先利用通用有限元软件ANSYS进行整体建模分析，整体分析中不考虑普通钢筋的建模，接着用专业软件桥梁博士对截面进行计算复核．从实际运营情况看，复核结果是合理的．

| Abstract: | Plane curved bridges are proposed with the high-grade highway construction and further development of urban construction, and reinforced concrete continuous rigid-frame curved slab bridges turn into one of the powerful competition bridges. In order to study the reinforced concrete continuous rigid-frame for the bending properties of space force, a reinforced concrete continuous rigid-frame curved slab bridge is introduced. Because curved bridges couldn＇t be analyzed commendably by plane software, finite element analysis of the bridge is established for spatial finite element software ANSYS, and ordinary steel modeling was not considered. On this basis, the checking of section is carried out by the plane software DR bridge. From the actual operating situation, the result is reasonable. |
