| 摘 要： | 以广东省粤赣高速公路新丰江特大桥施工监控为例,研究了相关关键参数的计算与控制,针对桥型特点,研究了合理的理论模型.考虑到某些计算过程中,部分采用平直桥代替有竖曲线桥的建模方案的可能性,重点研究了竖曲线对预拱度和应力计算结果的影响,讨论了相关误差控制的措施.

| Abstract: | In this paper, calculation and control of relevant key parameters are studied by taking construction control for especially large-scale bridge for on Xinfeng River as an example and the rational theory model is also studied to the bridge type characteristic. In some calculational processes, the modeling scheme with vertical curve bridge replaced by straight bridge partially is possible, so the influence of vertical curve to the calculating result of the pre-camber and the stress are analyzed emphatically. The relevant measures of error controlling are discussed at last. |
