互通立交中曲线梁设计
|
摘要
结合常州市高架道路工程中龙江路互通立交的匝道设计,较深入地探讨了曲线梁桥设计实践中涉及到的力学计算方法、结构分析、预偏心的合理设置、预应力束及普通钢筋配置方法等技术问题,另外对曲线梁桥的构造要求也进行了讨论。以供对此类曲线梁桥设计人员借鉴。
Combined with the ramp design of Longjiang Road Interchange in Changzhou Elevated Highway Project, this paper further discusses the technical problems in the mechanics calculation method, structure analysis, reasonable setting of pre-eccentricity, and location methods of pre-stressing tendons and regular reinforcement involved in the design practices of curved beam bridge, and discusses the construction requirements of curved beam bridge, which can be referred by the designers of the similar curved beam bridges.
